I do have a lifetime license for SpyShelter Premium. Maybe I'll give it a shot later this week. I may need to diagnose the system's performance by uninstalling some apps, because my PC crashed today for no reason. I just had Windows Live Writer and FireFox running, and when I tried to awake the PC from sleep mode, it wouldn't. Realizing that it had crashed, I tried a hard reset.
It would just boot to Startup repair and after a while, prompt me if I wanted to try a System Restore. But it was to no avail, and after a few failed repair attempts, I decided to try booting into other modes, like LGKC (Last Known Good Configuration) and Safe Mode. Luckily LKGC worked fine, and I was able to boot up and backed up a fresh copy of the System Image on to my External Drive, and burnt a System Repair disc on to a dvd. Phew!
Unfortunately there were no system dumps to analyze the issue. Just my luck. :-/
