Need Serious Computer Help!

I think my msn is giving me viruses I signed on MSN and a Bunch of Random Websites opened up within 10 seconds (150 Websites to be exact) I had to shut down my computer ... when I ran my anti virus it said I had 4 Trojans. I have no idea how long I've had them, what else should I do?

 

Scan your computer multiple times with different programs, back everything up as well.

 

Avast!
Hijackthis
AVG
etc. download and scan scan scan.

 

Save all important files on an external hard drive or USB drive...reinstall...

 

First things first, make sure you aren't on the internet on the infected computer. Secondly, it isn't your MSN that is giving you viruses. What AV do you have installed on the computer?

On the infected computer (without internet connected) go to Task Manager and look for suspicious processes running. Ones like services.exe. It is a System program, but if it was a "hidden" virus it would say the computer's name instead.

Since your AV didn't catch it, you may need to install a separate one from an installation disc, flash drive, or an external HD, and try to scan it with that. Avast! is good, and i've heard Kaspersky is also good.


Hopefully the info helped. Also, wrong section =/.
