A relative of mine wanted to use Prevx, but only when needed. So, I removed protection with the option to only enable it back on reboot, or by right-clicking the tray bar icon and click Load. The thing is, from time to time, Prevx keeps on coming back, including the scan before reloading protection. Scheduled scans are disabled. I've also experienced this myself, sometime ago... but since I don't really use Prevx, I never gave it much concern. Has anyone ever experienced this?
