lets talk some history of viruses: do you know which one is the most deadliest virus till 2010??

[Tophat]

MyDoom or Klez-H are 2 of the worst viruses ever! I think that any virus is nasty and is bad enough, even if it doesnt do as much damage as either of the above.

Have you heard of Virut or Sality?

[Tophat]

I have heard of them, but having just read about them:

Virut creates a backdoor and deletes .exe files, when you scan with a virus scanner, it will normally delete it as uncleanable. Eventually you end up loosing more and more files. The only viable alternative is to format the system.

Sality.Q is an appending polymorphic file infector that uses an entry point obscuring technique. Unlike other file infectors that modify the entry point of the host file to point to the virus code, Sality.Q replaces 122 bytes from the beginning code of the host file with its decryption routine and hides it in its code. It stores the original code 1,422 bytes away from the start of the last section.

That doesnt sound good either

The Michelangelo virus.

This virus can run rampant on your computer for months and you won't notice that anything is wrong. That is because even though your hard disk's master boot record is infected with the virus, the destructive code has not yet been executed. The virus is programmed to trigger its destructive code on March 6, Michelangelo's birthday. Talk about sneaky eh?

"... Fastest worm in history - it doubled in size every 8.5 seconds at its peak. From the time it began to infect hosts (around 05:30 UTC) on Saturday, Jan. 25, 2003 it managed to infect more than 90 percent of the vulnerable hosts within 10 minutes using a well known vulnerability in Microsoft's SQL Server. Slammer eventually infected more than 75,000 hosts, flooded networks all over the world, caused disruptions to financial institutions, ATMs, and even an election in Canada.

I vote for virut. Because like others have said it messes with exe and most the time you need to just do a totaly reformat because you could do clean up on it and afterwards you can re do/check out the system and see many new infections by virut.. And virut you shouldnt save anything with exe files to your new computer.
