Does anyone know how to check a Hijackthis log? I tried several of the on-line log analysers but don't have much faith in them since the 3 I tried all gave different analyses of the same logfile. The problem I'm trying to crack is that the "system" process has started using 50% of the CPU when nothing is active (not the "System Idle process"). It started after my daughter used my system for Facebook. I went back to a prior checkpoint and it went away, but now it is back and nothing I've tried seems to find/fix/change it.
I've run full scans using MacAfeee, Symantic and Adaware. Adaware found one file I removed and for a while the "system" process when back to using no cpu after I rebooted, but now it is back to 50% and re-running both scans doesn't pull up anything.
The other symptom is that when I tell the system to shutdown it eventually stops doing stuff but never shuts down or gives the "safe to shutdown" message. Sometimes it will go to a blank screen, sometimes it just stops still on the Windows is shutting down screen. It has all the updates except XP SP3 which I was told by the IT people at work not to install as they were having problems that after installing SP3 none of the systems could access any printers.
