When I had Prevx 2 installed along with my AntiVirus the Windows Security Center read that it found more than one Antivirus. When I uninstalled the AV I had at the time, WSC read that Prevx 2.0 was running. Ok so far so good as Prevx supposedly can be used by itself. When I uninstalled Prevx however with no AV installed, guess what? WSC read that Prevx 2.0 isn't turned on. It gets better. I did the old reliable procedure of turning off Windows Management Instrumentation Service and deleted the Repository Folder, restarted WMI and rebooted. Guess what? WSC reads Prevx 2.0 isn't turned on. When I install an AV though the WSC at least no longer reads it has found more than one AV. I believe I did the deletion procedure properly, and I must say I'm stumped. I did a search of the registry an some keys come up, but not sure if they are connected to Prevx. Just curious if anyone else experienced this and fixed it?
