The Virus Killed My PC

Yesterday, My new PC was down:any anti-virus software could not be installed and any web page marked by the key words "anti-virus" was auto closed, and also any anti-virus sofrware could not work... I have used the famous software kaspersky--KIS7.0 for a long time, which protests my PC in secure, but unfountely it was shut down by the virus this time...i had been looking for the strong virus named "av-killed" for the whole evening...finally,I gave up because of the virus' performation, which killed my PC...insteadly,i spent lots of time on re-installing the whole operation system.

I think the virus was transmitted as an attachment from the Internet when i was surfing the net paying no attention to it, what was worse, i did it without any anti-virus software installed at first!  there were no method i can use to clear the virus...how terrible the virus was!! Be careful from now on...
