Decided to do a clean install, having been installing new builds on top of previous since 220.127.116.11, and hoping to integrate Prevx nicely into Action Centre, and, hopefully, also see improved performance from boot-time splash screen. Even after using Uninstall tool, CCleaner, then reboot, was surprised to see splash-screen appear-then system locked-up. When re-booted still showed Prevx installed, so ran a scan to make sure I wasn't seeing things! Then tried to uninstall again, via trusty Revo, which seemed to go ok, re-booted- result: Prevx gone, then another freeze-up etc. Tried Safe mode now and found an empty Prevx folder, and apparantly uninstalled. Rebooted-another freeze-up- found MBAM IP Protection module now disabled + error (ss attached), plus Kaspersky wouldn't scan. To cut a long story short I did a System Restore finally, and saved a deep-scan log, which I'll send to Joe, if he wishes. What I thought might take 5 or 10 minutes took 1 1/2 hours(!!), and now I'm not really sure if it's installed ok now, even though it appears to be. Windows7 x86 + KIS 2010, MBAM, Zemana AL.
