What to Do If Your Computer Is Infected

Sometimes even an experienced user will not realise that a computer is infected with a virus. This is because viruses can hide among regular files, or camoflage themselves as standard files. This section contains a detailed discussion of the symptoms of virus infection, how to recover data after a virus attack and how to prevent data from being corrupted by malware.

Symptoms of infection

There are a number of symptoms which indicate that your computer has been infected. If you notice "strange things" happening to your computer, namely:

  • unexpected messages or images are suddenly displayed
  • unusual sounds or music played at random
  • your CD-ROM drive mysteriously opens and closes
  • programs suddenly start on your computer
  • you receive notification from your firewall that some applications have attempted to connect to the Internet, although you did not initiate this, then it is very likely that your computer has been infected by a virus

Additionally, there are some typical symptoms which indicate that your computer has been infected via email:

  • your friends mention that they have received messages from your address which you know you did not send
  • your mailbox contains a lot of messages without a sender's e-mail address or message header

These problems, however, may not be caused by viruses. For example, infected messages that are supposedly coming from your address can actually be sent from a different computer.

There is a range of secondary symptoms which indicate that your computer may be infected:

  • your computer freezes frequently or encounters errors
  • your computer slows down when programs are started
  • the operating system is unable to load
  • files and folders have been deleted or their content has changed
  • your hard drive is accessed too often (the light on your main unit flashes rapidly)
  • Microsoft Internet Explorer freezes or functions erratically e.g. you cannot close the application window

90% of the time the symptoms listed above indicate a hardware or software problem. Although such symptoms are unlikely to be caused by a virus, you should use your antivirus software to scan your computer fully.

What you should do if you notice symptoms of infection

If you notice that your computer is functioning erratically

  1. Don't panic! This golden rule may prevent the loss of important data stored in your computer and help you avoid unnecessary stress.
  2. Disconnect your computer from the Internet.
  3. If your computer is connected to a Local Area Network, disconnect it.
  4. If the computer cannot boot from the hard drive (error at startup), try to start the system in Safe Mode or from the Windows boot disk
  5. Before taking any action, back up all critical data to an external drive (a floppy disk, CD, flash memory, etc.).
  6. Install antivirus software if you do not have it installed.
  7. Download the latest updates for your antivirus database. If possible, do not use the infected computer to download updates, but use a friend's computer, or a computer at your office, an Internet cafe, etc. This is important because if you are connected to the Internet, a virus can send important information to third parties or may try to send itself to all email addresses in your address book. You may also be able to obtain updates for your antivirus software on CD-ROM from the software vendors or authorized dealers.
  8. Perform a full system scan.

If no viruses are found during a scan

If no viruses are found during the scan and the symptoms that alarmed you are classifed, you probably have no reason to worry. Check all hardware and software installed in your computer. Download Windows patches using Windows Update. Deinstall all unlicensed software from your computer and clean your hard drives of any junk files.

If viruses are found during a scan

A good antivirus solution will notify you if viruses are found during a scan, and offer several options for dealing with infected objects.

In the vast majority of cases, personal computers are infected by worms, Trojan programs, or viruses. In most cases, lost data can be successfully recovered.

  1. A good antivirus solution will provide the option to disinfect for infected objects, quarantine possibly infected objects and delete worms and Trojans. A report will provide the names of the malicious software discovered on your computer.
  2. In some cases, you may need a special utility to recover data that have been corrupted. Visit your antivirus software vendor's site, and search for information about the virus, Trojan or worm which has infected your computer. Download any special utilities if these are available.
  3. If your computer has been infected by viruses that exploit Microsoft Outlook Express vulnerabilities, you can fully clean your computer by disinfecting all infected objects, and then scanning and disinfecting the mail client's databases. This ensures that the malicious programs cannot be reactivated when messages which were infected prior to scanning are re-opened. You should also download and install security patches for Microsoft Outlook Express.
  4. Unfortunately, some viruses cannot be removed from infected objects. Some of these viruses may corrupt information on your computer when infecting, and it may not be possible to restore this information. If a virus cannot be removed from a file, the file should be deleted.

If your computer has suffered a severe virus attack

Some viruses and Trojans can cause severe damage to your computer:

  1. If you cannot boot from your hard drive (error at startup), try to boot from the Windows rescue disk. If the system can not recognize your hard drive, the virus has damaged the disk partition table. In this case, try to recover the partition table using scandisk, a standard Windows program. If this does not help, contact a computer data recovery service. Your computer vendor should be able to provide contact details for such services.

If you have a disk management utility installed, some of your logical drives may be unavailable when you boot from the rescue disk. In this case, you should disinfect all accessible drives, reboot from the system hard drive and disinfect the remaining logical drives.

  1. Recover corrupted files and applications using backup copies after you have scanned the drive containing this data.

Diagnosing the problem using standard Windows tools

Although this is not recommended unless you are an experience user, you may wish to:

  • check the integrity of the file system on your hard drive (using CHKDSK program) and repair file system errors. If there are a large number of errors, you must backup the most important files to removable storage media before fixing the errors
  • scan your computer after booting from the Windows rescue disk
  • use other standard Windows tools, for example, the scandisk utility

For more details on using these utilities, refer to the Windows Help topics.

If nothing helps

If the symptoms described above persist even after you have scanned your computer, and checked all installed hardware and software and your hard drive using Windows utilities, you should send a message with a full description of the problem to your antivirus vendor's technical support department.

Some antivirus software developers will analyse infected files submitted by users.

After you have eradicated the infection

Once you have eradicated the infection, scan all disks and removable storage media that may be infected by the virus.

Make sure that you have appropriately configured antivirus software installed on your computer.

Practice safe computing.

All of these measures will help prevent your computer getting infected in the future.

Who Writes Malicious Programs and Why?

Virus writers: four general types

Virus writers belong to one of four broad groups: cyber-vandals, who can be divided into two categories, and more serious programmers, who can again be split into two groups.

Cyber vandalism - stage 1

In the past, most malware was written by young programmers: kids who just had learned to program who wanted to test their skills. Fortunately most of these programs did not spread widely - the majority of such malware died when disks were reformatted or upgraded. Viruses like these were not written with a concrete aim or a definite target, but simply for the writers to assert themselves.

Cyber vandalism - stage 2

The second largest group of contributors to malware coding were young people, usually students. They were still learning programming, but had already made a conscious decision to devote their skills to virus writing. These were people who had chosen to disrupt the computing community by committing acts of cyber hooliganism and cyber vandalism. Viruses authored by members of this group were usually extremely primitive and the code contained a large number of errors.

However, the development of the Internet provided space and new opportunities for these would-be virus writers.Numerous sites, chat rooms and other resources sprang up where anyone could learn about virus writing: by talking to experienced authors and downloading everything from tools for constructing and concealing malware to malicious program source code.

Professional virus writers

And then these 'script kiddies' grew up. Unfortunately, some of them did not grow out of virus writing. Instead, they looked for commercial applications for their dubious talents. This group remains the most secretive and dangerous section of the computer underground: they have created a network of professional and talented programmers who are very serious about writing and spreading viruses.

Professional virus writers often write innovative code designed to penetrate computers and networks; they research software and hardware vulnerabilities and use social engineering in original ways to ensure that their malicious creations will not only survive, but also spread widely.

Virus researchers: the 'proof-of-concept' malware authors

The fourth and smallest group of virus writers is rather unusual. These virus writers call themselves researchers, and they are often talented programmers who devote their skills to developing new methods for penetrating and infecting systems, fooling antivirus programs and so forth. They are usually among the first to penetrate new operating systems and hardware. Nevertheless, these virus writers are not writing viruses for money, but for research purposes. They usually do not spread the source code of their 'proof of concept viruses', but do actively discuss their innovations on Internet resources devoted to virus writing.

All of this may sound innocent or even beneficial. However, a virus remains a virus and research into new threats should be conducted by people devoted to curing the disease, not by amateurs who take no responsibility for the results of their research. Many proof of concept viruses can turn into serious threats once the professional virus writers gain access to them, since virus writing is a source of income for this group.

Why write viruses?

Fraud

The computer underground has realised that paid for Internet services, such as Internet access, email and web hosting, provides new opportunities for illegal activity with the additional satisfaction of getting something for nothing. Virus writers have authored a range of Trojans which steal login information and passwords to gain free access to other users' Internet resources.

The first password stealing Trojans appeared in 1997: the aim was to gain access to AOL. By 1998 similar Trojans appeared for all other major Internet service providers. Trojans stealing log in data for dial-up ISPs, AOL and other Internet services are usually written by people with limited means to support their Internet habit, or by people who do not accept that Internet resources are a commercial service just like any other, and must therefore be paid for.

For a long time, this group of Trojans constituted a significant portion of the daily 'catch' for antivirus companies worldwide. Today, the numbers are decreasing in proportion to the decreasing cost of Internet access.

Computer games and software license keys are another target for cyber fraud. Once again, Trojans providing free access to these resources are written by and for people with limited financial resources. Some hacking and cracking utilities are also written by so-called 'freedom fighters', who proclaim that all infomration should be shared freely throughout the computing community. However, fraud remains a crime, no matter how noble the aim is made out to be.

Organised cyber crime

The most dangerous virus writers are individuals and groups who have turned professional. These people either extract money directly from end users (either by theft or by fraud) or use zombie machines to earn money in other ways, such as creating and selling a spamming platform, or organizing DoS attacks, with the aim here being blackmail.

Most of today's serious outbreaks are caused by professional virus writers who organize the blanket installations of Trojans to victim machines. This may be done by using worms, links to infected sites or other Trojans.

Bot networks

Currently, virus writers either work for particular spammers or sell their wares to the highest bidder. Today, one standard procedure is for virus writers to create bot networks, i.e. networks of zombie computer infected with identical malicious code. In the case of networks used as spamming platforms, a Trojan proxy server will penetrate the victim machines. These networks number from a thousand to tens of thousands of infected machines. The virus writers then sell these networks to the highest bidder in the computer underground.

Such networks are generally used as spamming platforms. Hacker utilities can be used to ensure that these networks run efficiently; malicious software is installed without the knowledge or consent of the user, adware programs can be camoflaged to prevent detection and deletion, and antivirus software may be attacked.

Financial gain

Apart from servicing spam and adware, professional virus writers also create Tojan spies which they use to steal money from e-wallets, Pay Pal accounts and/or directly from Internet bank accounts. These Trojans harvest banking and payment information from local machines or even corporate servers and then forward it to the master.

Cyber extortion

The third major form of contemporary cyber crime is extortion or Internet rackets. Usually, virus writers create a network of zombie machines capable of conducting an organized DoS attack. Then they blackmail companies by threatening to conduct a DoS attack against the corporate website. Popular targets include estores, banking and gambling sites, i.e. companies whose revenues are generated directly by their on-line presence.

Other malware

Virus writers and hackers also ensure that adware, dialers, utilities that redirect browsers to pay-to-view sites and other types of unwanted software function efficiently. Such programs can generate profits for the computer underground, so it's in the interests of virus writers and hackers to make sure that these programs are not detected and are regularly updated.

In spite of the media attention given to young virus writers who manage to cause a global epidemic, approximately 90% of malicious code is written by the professionals. Although all of four groups of virus writers challenge computer security, the group which poses a serious, and growing threat is the community of professional virus writers who sell their services.

Indian economy will not be affected as badly as other countries by the global financial crisis as it has a strong growth record, Jamie Dimon, chief executive of financial services firm JP Mrgan Chase, said.

"India is doing far better than most other countries. Most important that you (India) might slow down a little bit but you have still a pretty good growth, so I don't think it needs to do quiet anything like it has been done elsewhere
," Dimon said in an interview with NDTV.

He, however, said that the global economic scenario was alarming and the current crisis was "worst since the great depression" of 1930s.

Referring to the great depression, he said: "I don't think it will go that bad but that will be the worst."

With the three major economies - the U.S, Europe and Japan - facing downturn, Dimon urged the emerging economies to be prepared to deal with its consequences.

"The three 3 major economies in the world are slowing down that it will have an effect on them (emerging economies)," he said.

23 Ways To Speed WinXP, Not only Defrag

Since defragging the disk won't do much to improve Windows XP performance, here are 23 suggestions that will. Each can enhance the performance and reliability of your customers' PCs. Best of all, most of them will cost you nothing.

1.) To decrease a system's boot time and increase system performance, use the money you save by not buying defragmentation software -- the built-in Windows defragmenter works just fine -- and instead equip the computer with an Ultra-133 or Serial ATA hard drive with 8-MB cache buffer.

2.) If a PC has less than 512 MB of RAM, add more memory. This is a relatively inexpensive and easy upgrade that can dramatically improve system performance.

3.) Ensure that Windows XP is utilizing the NTFS file system. If you're not sure, here's how to check: First, double-click the My Computer icon, right-click on the C: Drive, then select Properties. Next, examine the File System type; if it says FAT32, then back-up any important data. Next, click Start, click Run, type CMD, and then click OK. At the prompt, type CONVERT C: /FS:NTFS and press the Enter key. This process may take a while; it's important that the computer be uninterrupted and virus-free. The file system used by the bootable drive will be either FAT32 or NTFS. I highly recommend NTFS for its superior security, reliability, and efficiency with larger disk drives.

4.) Disable file indexing. The indexing service extracts information from documents and other files on the hard drive and creates a "searchable keyword index." As you can imagine, this process can be quite taxing on any system.

The idea is that the user can search for a word, phrase, or property inside a document, should they have hundreds or thousands of documents and not know the file name of the document they want. Windows XP's built-in search functionality can still perform these kinds of searches without the Indexing service. It just takes longer. The OS has to open each file at the time of the request to help find what the user is looking for.

Most people never need this feature of search. Those who do are typically in a large corporate environment where thousands of documents are located on at least one server. But if you're a typical system builder, most of your clients are small and medium businesses. And if your clients have no need for this search feature, I recommend disabling it.

Here's how: First, double-click the My Computer icon. Next, right-click on the C: Drive, then select Properties. Uncheck "Allow Indexing Service to index this disk for fast file searching." Next, apply changes to "C: subfolders and files," and click OK. If a warning or error message appears (such as "Access is denied"), click the Ignore All button.

5.) Update the PC's video and motherboard chipset drivers. Also, update and configure the BIOS. For more information on how to configure your BIOS properly, see this article on my site.

6.) Empty the Windows Prefetch folder every three months or so. Windows XP can "prefetch" portions of data and applications that are used frequently. This makes processes appear to load faster when called upon by the user. That's fine. But over time, the prefetch folder may become overloaded with references to files and applications no longer in use. When that happens, Windows XP is wasting time, and slowing system performance, by pre-loading them. Nothing critical is in this folder, and the entire contents are safe to delete.

7.) Once a month, run a disk cleanup. Here's how: Double-click the My Computer icon. Then right-click on the C: drive and select Properties. Click the Disk Cleanup button -- it's just to the right of the Capacity pie graph -- and delete all temporary files.

8.) In your Device Manager, double-click on the IDE ATA/ATAPI Controllers device, and ensure that DMA is enabled for each drive you have connected to the Primary and Secondary controller. Do this by double-clicking on Primary IDE Channel. Then click the Advanced Settings tab. Ensure the Transfer Mode is set to "DMA if available" for both Device 0 and Device 1. Then repeat this process with the Secondary IDE Channel.

9.) Upgrade the cabling. As hard-drive technology improves, the cabling requirements to achieve these performance boosts have become more stringent. Be sure to use 80-wire Ultra-133 cables on all of your IDE devices with the connectors properly assigned to the matching Master/Slave/Motherboard sockets. A single device must be at the end of the cable; connecting a single drive to the middle connector on a ribbon cable will cause signaling problems. With Ultra DMA hard drives, these signaling problems will prevent the drive from performing at its maximum potential. Also, because these cables inherently support "cable select," the location of each drive on the cable is important. For these reasons, the cable is designed so drive positioning is explicitly clear.

10.) Remove all spyware from the computer. Use free programs such as AdAware by Lavasoft or SpyBot Search & Destroy. Once these programs are installed, be sure to check for and download any updates before starting your search. Anything either program finds can be safely removed. Any free software that requires spyware to run will no longer function once the spyware portion has been removed; if your customer really wants the program even though it contains spyware, simply reinstall it. For more information on removing Spyware visit this Web Pro News page.

11.) Remove any unnecessary programs and/or items from Windows Startup routine using the MSCONFIG utility. Here's how: First, click Start, click Run, type MSCONFIG, and click OK. Click the StartUp tab, then uncheck any items you don't want to start when Windows starts. Unsure what some items are? Visit the WinTasks Process Library. It contains known system processes, applications, as well as spyware references and explanations. Or quickly identify them by searching for the filenames using Google or another Web search engine.

12.) Remove any unnecessary or unused programs from the Add/Remove Programs section of the Control Panel.

13.) Turn off any and all unnecessary animations, and disable active desktop. In fact, for optimal performance, turn off all animations. Windows XP offers many different settings in this area. Here's how to do it: First click on the System icon in the Control Panel. Next, click on the Advanced tab. Select the Settings button located under Performance. Feel free to play around with the options offered here, as nothing you can change will alter the reliability of the computer -- only its responsiveness.

14.) If your customer is an advanced user who is comfortable editing their registry, try some of the performance registry tweaks offered at Tweak XP.

15.) Visit Microsoft's Windows update site regularly, and download all updates labeled Critical. Download any optional updates at your discretion.

16.) Update the customer's anti-virus software on a weekly, even daily, basis. Make sure they have only one anti-virus software package installed. Mixing anti-virus software is a sure way to spell disaster for performance and reliability.

17.) Make sure the customer has fewer than 500 type fonts installed on their computer. The more fonts they have, the slower the system will become. While Windows XP handles fonts much more efficiently than did the previous versions of Windows, too many fonts -- that is, anything over 500 -- will noticeably tax the system.

18.) Do not partition the hard drive. Windows XP's NTFS file system runs more efficiently on one large partition. The data is no safer on a separate partition, and a reformat is never necessary to reinstall an operating system. The same excuses people offer for using partitions apply to using a folder instead. For example, instead of putting all your data on the D: drive, put it in a folder called "D drive." You'll achieve the same organizational benefits that a separate partition offers, but without the degradation in system performance. Also, your free space won't be limited by the size of the partition; instead, it will be limited by the size of the entire hard drive. This means you won't need to resize any partitions, ever. That task can be time-consuming and also can result in lost data.

19.) Check the system's RAM to ensure it is operating properly. I recommend using a free program called MemTest86. The download will make a bootable CD or diskette (your choice), which will run 10 extensive tests on the PC's memory automatically after you boot to the disk you created. Allow all tests to run until at least three passes of the 10 tests are completed. If the program encounters any errors, turn off and unplug the computer, remove a stick of memory (assuming you have more than one), and run the test again. Remember, bad memory cannot be repaired, but only replaced.

20.) If the PC has a CD or DVD recorder, check the drive manufacturer's Web site for updated firmware. In some cases you'll be able to upgrade the recorder to a faster speed. Best of all, it's free.

21.) Disable unnecessary services. Windows XP loads a lot of services that your customer most likely does not need. To determine which services you can disable for your client, visit the Black Viper site for Windows XP configurations.

22.) If you're sick of a single Windows Explorer window crashing and then taking the rest of your OS down with it, then follow this tip: open My Computer, click on Tools, then Folder Options. Now click on the View tab. Scroll down to "Launch folder windows in a separate process," and enable this option. You'll have to reboot your machine for this option to take effect.

23.) At least once a year, open the computer's cases and blow out all the dust and debris. While you're in there, check that all the fans are turning properly. Also inspect the motherboard capacitors for bulging or leaks. For more information on this leaking-capacitor phenomena, you can read numerous articles on my site.


Following any of these suggestions should result in noticeable improvements to the performance and reliability of your customers' computers. If you still want to defrag a disk, remember that the main benefit will be to make your data more retrievable in the event of a crashed drive.

23.) At least once a year, open the computer's cases and blow out all the dust and debris. While you're in there, check that all the fans are turning properly. Also inspect the motherboard capacitors for bulging or leaks. For more information on this leaking-capacitor phenomena, you can read numerous articles on my site.


Following any of these suggestions should result in noticeable improvements to the performance and reliability of your customers' computers. If you still want to defrag a disk, remember that the main benefit will be to make your data more retrievable in the event of a crashed drive.

Two easy ways to download youtube videos.
many people already know how to do this but i just thought i'd write this for those that don't.

The first method is as easy as cut and paste. just copy the url of the youtube video you require. then take it to the website below and paste the url in the box. Once you press the button the file will begin downloading.

http://video.qooqle.jp/dl/

only problem using this method is that you require an flv player to view files. if that doesn't bother you then you can download an flv player from here.

http://www.download.com/FLV-Player/3...-10467082.html.


The second method is just the same cut and paste job as the first, only take it to this site instead...

http://vixy.net/

once you get the youtube video url pasted into the box on vixy.net, you then have the option to convert the file into a number of formats.
mov
avi
mp4 -- for ipod
3gp -- for mobile
mp3 -- just the sound

just select the format you desire and download and it will be converted and downloaded to your computer. easy enough!

3 ways to get IP of a person


Obtaining an IP from MSN Messenger.
----------------------------------

Firstly we learn the method used by most people when they want to get
someone elses IP Address.

Step 1 - Start MSN Messenger and login as yourself.

Pg.17

Step 2 - Hit your "Start" button and click run. Type into the white box
"Command" (without the quotation marks)

Step 3 - Type in "Netstat -N" (without the quotation marks) into the
black box and hit enter.

Step 4 - Start a conversation with your 'victim' and send them a file.
Once they accept the file Hit your "Start" button and click run. Type
into
the white box "Command" (without the quotation marks) and Type in
"Netstat -N" (without the quotation marks) into the black box and hit
enter.

Step 5 - Look in the middle column of both your MS Dos boxes and look
in the newer wndow for the IP address that has magically appeared in
the middle column. This is your victim's IP Address.

Obtaiing an IP from an E-Mail.
-------------------------------

Ok, lets say the person does not use MSN Messenger (can't blame them)
we can get an IP address from most E-Mail address. In this example we
shall use Outlook Express to view the E-Mails in.

Step 1 - Load Outlok express and left click on an E-Mail that was sent
from your 'victim'

Step 2 - Right click this E-Mail and click the "Properties" button.

Step 3 - Now Click on the tab displaying as it's text "Details" and
look for the buttom saying "Message Source", once found (not hard) click it.

Step 4 - Look in all the jargon for something like "X-Originating-IP: "
with a number after the colon. This number is the sender's IP Address.

Step 5 - If you cannot find "X-Originating-IP: " then do not worry.
Look for instead "Received:", and go along this string untill you come
to a nuber in brackets, this however maybe an IP but it might not be
the IP address of the 'victim', infact if they sent the E-Mail from a
we E-Mail service (like hotmail.com) then chances are it is not their
IP address.

Obtaiing an IP from Physical Access.
------------------------------------

If you have physical access to a computer then getting the IP address
is simple.

Step 1 - Click the "Start" button and hit "Run". Type in "Command" and
hit enter.

Step 2 - Type in "ipconfig" OR "winipcfg" and hit enter now look for
where it says "IP Address:", next to this is the IP of the computer you
are using.
