I am running Windows 7 Home Premium Service Pack 1, 64 bit, on an Acer Aspire M3970 Desktop. Intel Core i5 - 2320 @ 3.00GHZ. 4 GB Ram.
It has run like a dream since I got it several years ago. In the past few weeks it has taken to running deathly slow after a period of inactivity - 15 minutes or more - regardless of the number of windows I have open at the time (one to numerous). It takes several minutes to close each window till I can finally reboot (which itself can take 10 minutes or more). It works fine after a reboot until I leave it inactive again and then the problem has returned. I have not installed any new software recently.
I am running Vipre Internet Security which updates every 30 minutes, and scans regularly (latest one last night). I have run Malwarebytes which does not detect any issues. Scannow run at the end of July shows issues in process 74 and 143, but not sufficient (I don't think) to cause the problem. I have uploaded those two.
Any assistance would be appreciated. Thanks.
