The World's Worst Viruses\n\n\nHere's a look at ten of the most malignant viruses and worms of all time.\n10. Surreptitious Sircam\n\nSircam appeared in July 2001 on PCs running Windows 95, 98, and Me. The worm appeared in e-mail in-boxes with an attachment; the body of the message was in Spanish or English. Typical greetings included "Hi! How are you?" and "Hola como estas?" If you launched the attachment, Sircam installed itself on the infected computer, then grabbed random documents and sent them out to e-mail addresses it captured from your address book. It also occasionally deleted files and filled the infected computer's hard drive with gibberish. Visit Symantec's Security Response for instructions on how to remove Sircam.\n9. Red Raider\n\nCode Red burned brightly in the summer of 2001, infecting hundreds of thousands of computers--mainly on corporate networks. Code Red slithered through a hole in Internet Information Server (IIS) software, which is widely used to power Internet servers, then scanned the Internet for vulnerable systems to infect and continue the process. The worm used contaminated PCs as weapons in denial of service attacks--flooding a Web site with a barrage of information requests. The original target was the official White House Web site, but government officials changed the site's IP address to thwart the attack.\n\nThe worm exploited a weakness in the IIS software (which has since been fixed with a patch from Microsoft) that allowed an intruder to run arbitrary code on a victimized computer. Multiple variants of this worm now exist. Visit Symantec's Security Response for instructions on how to protect your system from Code Red.\n8. Bad Benjamin\n\nBenjamin--a new breed of worm--was let loose in May 2002, and it affected users of the popular file-sharing program Kazaa. The crafty worm posed as popular music and movie files. Kazaa users thought they were downloading a media file to their machines, but they got the imposter instead. It then set up a Kazaa share folder and stuffed it with copies of itself posing as popular music and movie files, which other Kazaa users would download. It congested the system's network connection and would ultimately fill up a hard drive. Visit Symantec's Security Response for instructions on how to remove Benjamin.\n7. Numbing Nimda\n\nNimda (also known as the Concept Virus) appeared in September 2001, attacking tens of thousands of servers and hundreds of thousands of PCs. The worm modified Web documents and executable files, then created numerous copies of itself. The worm spread as an embedded attachment in an HTML e-mail message that would execute as soon as the recipient opened the message (unlike the typical attached virus that requires manual launching of the attachment). It also moved via server-to-server Web traffic, infected shared hard drives on networks, and downloaded itself to users browsing Web pages hosted on infected servers. Nimda soon inspired a crowd of imitators that followed the same pattern. Visit Symantec's Security Response for the Nimda removal tool.\n6. Tennis Anyone?\n\nThe Anna Kournikova (or VBS.SST@mm) worm, appearing in February 2001, didn't cause data loss, although in the process of boosting the profile of its namesake, the Russian tennis player, it did cause embarrassment and disruption for many personal and business users. The worm showed up in Microsoft Outlook users' e-mail in-boxes with an attachment (supposedly a picture of Kournikova). The attachment proved hard to resist. The result? Clicking the bogus attachment sent copies of the worm via e-mail to all addresses found in the victim's Outlook address book. Kournikova also brought about a number of copycat variants. Visit Symantec's Security Response for instructions on how to remove Kournikova.\n\nMost worm creators have never been identified, but a 21-year-old Dutchman, Jan de Wit, admitted to unleashing

Avast is the best currently.\nYou can get it here:\nhttp://www.avast.com/\n\n(Avast (Home edition(free)) is the only anti virus which on my PC has tracked every single virus. I tried norton (many times it failed especially when the virus was on a pendrive(usb v1.1 @ 124 kb/s) (it usually ended up locking my system despite its high system specs)  ,macafee (Slowed the startup and boot up times), avg (took too long to startup and at times failed to update unless the system was restarted )\nEdit : Avast also support Vista and soon will support x64)

Depends entirely on the type of virus ... visit Symantec or Trend Micro and enter the name of the virus into their search engines ... you should be able to download a removal tool or at least instruction on how to remove it

In addition to Hybrid's answer:\n\nDepending on the severity/quantity of viruses, you may want to look into:\n\n1) If you have an anti-virus program, run a full scan on your system. Look for McAffee or Norton antivirus tools in "programs" for starters.\n\n2) If you have no antivirus program installed, try AVG free addition. It is easy to install and you'll receive regular updates to counter new virus attacks. You can also use tools to run full scans on your system. You can download it at: http://free.grisoft.com/doc/2/lng/us/tpl...\n\nOr, try the following link:\nhttp://housecall.trendmicro.com/...\n\n3) If a PC is plagued with viruses, your best bet is to clean the system BEFORE it boots. This can be done by using some free tools available. Check out:\n\nhttp://www.nu2.nu/pebuilder/intro/...\n\nYou use PE Builder to make a bootable CDROM that loads a windows-like interface in memory. Because none of your hard drive files are locked they can be cleaned of any viruses. BartPE provides free McAffee plugins that you can run to accomplish this. WARNING: you have to fairly computer savy to work with BartPE. You may want to recruit a friend to help. It's more work, but I've found this to be the most effective way to clean your system.\n\nHTH,\nD

There's also a scanner on Microsoft's website that will scan for viruses and help remove them. \n\nI figure it's the least they could do for allowing so many problems. :)

To all those who say norton antivirus is the best you are suckers for marketing, Norton is the single worst AV that has ever existed not only does it cause blue screens in windows, norton is usually one of the last to produce fixes for viruses. I have never had a problem with AVG and in the last year or so that i have removed Norton and installed AVG i have seen better preformance from my comp and am yet to have a virus (except for when i removed norton installed AVG and found 10 viruses that good old norton failed to pick up)

It highly depends on the type of virus.  Ranging from a mere trojan to a biobomb what you may have to do varies.\n\nIf its a trojan get an antivirus like avast and run it then get a decent firewall and install that to help prevent future occurences.\n\nIf its really bad and your comp starts with a blue screen or worse wont start at all.  You could need to either wipe your bios, your harddrive, or worst of all buy a new motherboard.\n\nHope its the former.

There has been a new virus just discovered called 'A (Virtual) Card for You.' It has been classed by Microsoft as the most destructive ever. It destroys Sector 0 of the HDD where functioning info is stored. It is sent by email to all contacts on the list and once opened, infects the pc. Hope you find this useful
