I was minding my own business the other day and accidentally clicked on some ad somewhere. Now, when using Firefox, my Google searches are re-directed, and over time the computer gradually gets slower and slower until nothing responds and I just have to power it off (usually after it's been on for half an hour or so). At first, I was able to use IE and avoid the slog issue, but now the redirects and sluggishness seem to be creeping in there too.
When the computer first comes up to the desktop, there is a flurry of disk activity that lasts for several minutes after the desktop appears. I have Avast installed, was using AVX before. I have run scans with AVX, Malwarebytes... both found Downloader (on a help dll) and removed it.
I have run GMER and found nothing out of the ordinary.
I installed ProcMon so I could try and figure out what is hitting the hard drive so much. As you might expect, it shows both services.exe and svchost.exe hitting every DLL in the system, doing who knows what? This happens on just about every reboot. Every several reboots the disk activity doesn't happen for some reason.
Anyway, I'm tired of running virus scans and finding nothing now. This sure feels like a rootkit, but GMER doesn't find it.
Thanks for your time. I eagerly await your instructions.
