Welcome to the Forum.
Start by trying a repair. Repair is accessed through the add/remove function (Program and Features) Select Avast,
scroll down if needed and select repair. When that finishes, Reboot your system.
Let us know if that works. If not, do a clean install of Avast. You'll find instruction by following the link in my signature.[/quote]
Thank you for the help and advice,
I tried the repair option, and rebooted, but no change. I still got the odd hand-up/freezing/CPU use=100% when I right click exe files that last for about 10-15 seconds.
After much trial and error I have found out it is with the 'File System Shield' that is the problem. Or more directly the packets part. I have ‘scan all packets’ enabled.
I tested this by disabled all packets and just keep the default selected (Self-extracting DOS executables, Self-extracting Win32 executables, Droppers, and NTFS streams are only enabled) and have NO problems at all!
I then went threw and enabled one package only and tested the problem.
I found out if I enable ‘Installer Archive’ at any time, I then have my PC freezes/hangs and CPU use is @ 100% for about 15 seconds or so.
Note: This didn’t happen in the old version, before I updated Avast to v2015.10.0.2208 that it is at now, I don’t know what was changed, but I’d like to know how to fix this permanently.
Thanks again!
