I was using ZoneAlarm free with another antivirus and a third antispyware program, and thought I'd had a go at reducing this by upgrading to ZoneAlarm security suite.After having purchased and installed it my computer has become almost unbearably slow.
Prior to installation the computer was fast, access to files was smooth, and when idle the computer would use between 0-4% CPU.After installation the computer is "laggy", access to files takes forever and when idle the computer typically uses between 10-50% CPU but sometimes peaks up to 80% CPU usage, doing nothing at all except running the "ScanningProcess.exe" processes (2).
After disabling the antivirus completely the problem seems at least a bit reduced, but that means I have to go back to my old antivirus which I was hoping not to have to.What can I do to solve this ? Why is antivirus consuming all the resources of the computer ?
