well, my symantec virus program keeps on telling me that it's catching a downloader/trojan horse virus (and i mean it says it finds one about every 5-8 seconds and i'm not exaggerating one bit) and yet every time i do a scan, it comes out negative.

however, there's a catch. i know i'm infected, because i was typing up a paper and while i was using my computer, programs kept on freezing for the weirdest reasons for example: i scrolled too quickly and my microsoft word program gave me the "not responding" sign. this is a very frustrating problem because i've run ewido twice and CCleaner whenever i've got a spare couple of minutes. my computer is performing incredibly slowly and i would like to know how to solve this problem immediately. i took a hijackthis log and this is what it looks like

(oh, and i've also run cwshredder...and it didn't find anything either. i'm more or less clueless when it comes to things like this, so i figure i'd ask someone who knows what they're doing. i've asked someone here before and i got perfect results so i'm sorry to be a bother, but i'm asking again)

If those pieces of anti-virus can't find it then it is more likely not to be a virus. These kind of warnings sometimes pop-up if you are connected to a p2p network or downloading via bit torrent. These programs can also slow down you PC. I can also see that you have some AOL software and I would advise that you steer clear of AOL! I am sure you will hav tried restarting your computer. Failing this try a system restore (start>accessories>system tools>System Resore). You will not loose any files.

Hope this helps.
