Answering the question “Task Manager shows 100% CPU utilization, but nothing in process list does.”, Paul Woodward stated that his problem with 100% CPU was a rootkit infecting his computer. My computer seems to suffer from the same problem.
Which software for Windows XP do you recommend for detecting and removing a rootkit?
Solution:
I don’t think you can actually use it to ‘clean’ a rootkit, but a very good ‘detector’ is RootkitRevealer from Sysinternals.
