which was the worst virus in your pc you have ever encountered.

Well this is not the worst virus out there, but is giving me headache "Win32/Sality". I am fighting with all the tools I have but this virus infects a lot of files. I have AVG Internet Security, AVG Identity Protection and AVG Win32/Sality Remover tool. Right now is under control, but I know is still there, somewhere in my computer.

I don't remember any serious damage from viruses lately but i did have my share of trojans in the past. The only serious thing i remember is a few years ago when i got this adult pop up that continued to show a few minutes after using browser and it appeared even when i restarted my pc. I remember it started at the worst time ever when my brother visited us for lunch and he is older and he blamed me but i didn't do anything. That actually happened twice and was annoying and didn't know how to fix it back than. Lately i don't have any problems and i solve them if they appear just hope i didn't talk to soon. Which was your worst virus?

I don't remember.. because i have a lot of virus on my system.. before some days.. but now i remove them by a good antivirus.. have a nice day and keep mylotting always..

Just a tip to everyone, Microsoft just came out with a Anti Virus software package that may help all of you. it has already saved me a few times, it's also free!
