A customer of mine is having a problem with Macfee 5.xx. It is updated with the scan engine and dat files. The thing is that when the system scan is enabled (doesnt matter if it is set for all files or just program files) it causes the computer to slow down to a horrible rate. It is to the point where it takes several seconds for even a single click to respond after the comp has been running for 20mins or so. When the system scan is disabled, and all other scanning is still enabled the system works fine. I have reinstalled it and cleaned the registry each time with the same end result, the problem is still there

Does anyone have any suggestions, the system is a 450p3 with 512 ram, win 98.
