I have several Windows 7 systems that I notice the process avastsvc.exe is using about 25-30% of the CPU when the file shield is active. This is affecting all other programs and causing them to lock up when opening or saving files. If I disable file shield avastsvc.exe drops to below 5% CPU load and the computer performance improves drastically. Has anyone else seen this? I see several posts for the free product that had the same issue and it was resolved by upgrading the software, but I am already running the latest version 8.0.1603. I have adjusted the heuristics and the sensitivity, but neither had an affect on the CPU load. Let me know if you have any ideas to troubleshoot this problem before the users burn me at the stake.
