Had a rootkit virus, 3 different scanners say it's gone, but

by roloro - 8/9/11 7:35 PM

I had a rootkit, Avast found it. It was fake AV ransomware, kept telling me if i would send 84$ all my problems would be fixed. One of the things it did was make my CPU usage run very high, between 70 and 100%. We cleaned it with Combofix. Subsequent scans with Avast, Clamwin, and Kaspersky all say my machine is clean. However, I am still having times when my CPU usage is very high, again between 70 and 100%.

Any ideas or help will be greatly appreciated :-)


System Info:
CPU- Intel Pentium(R) D 3.40gigahertz (3391.59megahertz)
Memory- 4 gig
OS- WindowsXP service pack 3 build 2600

Two things

Two things

1: Once you have been infected with a rootkit, the only 100% sure way to be rid of EVERYTHING, is to format the system and start clean. You never know if that rootkit downloaded and installed some secondary infection, and whether any of those then downloaded a tertiary infection, etc.

2: Since it's XP we're talking about, have you checked for the DMA bug?

And ask the big question. After over a decade, why is that bug still alive?
