After PC is on it starts to get sluggish to the point of becoming unusable until reboot, and all is fine after reboot until it slows down again. It will start out by just seeming a bit slow, then even things like typing get delayed or opening or closing windows. A few times it got so bad it appeared that the screen wouldn't even refresh.
PC is Vista 64 SP2 with 8GB RAM. I see no new or suspicious processes or resources; disc activity, CPU, and memory usage seem normal. The problem does not seem to occur with any particular application.
What I've Done:
HP hardware scan - ok
Everest scan - ok
Norton 360 complete scan - ok
Malwarebytes scan - OK
Rootkit Revealer - app crash every time I run
Sophos Anti-Rootkit - found hidden files, all seem legit
