Has this issue been touched on already? Couldn't find it in the help file, but that's probably not surprising. Anyway, I had some slowdowns with the free version of prevx and wanted to try and uninstall one at a time the latest additions to my system to figure out what didn't play well. I used the unistall tab from the start menu>programs>prevx3.0, and without hardly any pause (fraction of a second) it returned with "uninstall will complete at next reboot" or something to that effect. But when I tried to boot, it froze. And every time after that too. Needless to say I had some trouble getting my system back to working order. System restore was no help, but eventually I managed to gain some semblance of normality, but for example Avast is no longer able to run on my system. It becomes disabled at reboot. Very strange. So, I wonder if anybody knows what hit me? And how can I fix it? Would it help to reinstall prevx and uninstall it with the uninstaller? What damage could have been done?
