Sorry all if this is redundant or covered elsewhere.... I am totally at wits end after 48 hours of trying to figure out what is wrong with my system. I know i have a hijack/virus/worm of some type but it must be a new variant because after scouring tons of help forums i can't see any messages that indicate others are having the same problem. Basically, I can't even download hijackthis, because my computer stops the download at 99%. CWshredder i can download, but i can't unzip the file (i end up with an undeletable and seemingly empty directory where the unzipped cwshredder should be). I'm running my computer in safe mode and at least my IE browser is no longer hijacked. After running NAV today I found (again) hxdefdrv.sys backdoor virus which was apparently removed...but NAV supposedly found and removed it yesterday also.. I'm going totally nuts with this thing...any help would be appreciated. Getting CWshredder and HJT running would be a good start, but I don't know how to proceed.
