My PC running XP Pro has been slower than molases lateley. A quick check of the Windows Task Manager shows that a process called System Idle Process is using anywhere from 30%-90% of the CPU, but only about 20k of memory. Does anyone have any idea what would cause this? I scan for viruses nightly, my virus definition files are up to date as well. Today I removed a bunch of junk using Adaware, but the problem remains.
