Short summary*: I'm playing an on-line game, now and again it slows up (ping goes way up, fps slows) and when I open Task Manager, the game speeds back up with no other action on my part. If I keep the Task Manager open, eventually the performance hit will recur after perhaps 10-15 minutes. I have to close Task Manager and re-open it for the fix to happen again.
My guess is the culprit is some built-in Windows feature/process/service that backs itself off for a time after it detects Task Manager has opened. (That, or some very subtle malware that doesn't want itself shown by Task Manager.)
Anyone have any ideas on performance-draining services/apps/malware that back off when Task Manager first starts?
Thanks in advance.
* a longer description would include having virus/malware protection on, active and updated; being up to date on Windows Update; running CCLeaner, Malware Bytes, and MS Malicious Software Detection; and taking snapshots before, during and after using Hijack This where no differences are shown; looking at Task Manager's list of processes and CPU usages, ....
