Crossroad Technologies We Make Computers Work For You

Hi,
Yesterday a friend of mine came to my place to drop him some music files into his usb. But into his usb, there were some other files, that he wasn’t able to recognise himself!
My pc started lagging, and therefore I was forced to do a reset.
When it opened, I formatted the usb just to be sure that no virus is on it, and then disaster started.
First of all, the antivirus starts and closes immediately. I’ve runned trojan remover 3 times , removed what was found but nothing… The virus is still here… And what do I mean? Internet Explorer windows pop-up every once in a while getting me into strange chinese sites.
In addition I can’t download many things from rapidshare (… when I press download firefox closes)! WinRar opens whatever it wants!
I’ve runned Eset Online Virusscan, and it found 10 viruses. I’ve made even a system recovery, but still nothing..
I have 2 hdds, and therefore if I must format them, I will lose all the important personal files of my.
So what to do? Back the files and format the hdds? Try another magical antivirus? or just get my pc done in a technician and get me ripped off?

If its a anti virus protector the only way you can, or the only way I could get rid of it was downloading a free malware program, even though I had one on my computer already..

Hope this helps.
