So I use System Mechanic by iolo, and besides a few hiccups (unable to scan my hard drives, causing sys mech to just close during hdd scan, not crash, just close, and it never finishes ssd optimization, gets stuck at 100%) it works for what I need it to do, general maintenance. Recently I believed I got a virus, one that played a random audio ad for crizal lenses, even when there were no ads anywhere, and so I did a round of sys mech and then some scanning. Part of the things I do with sys mech is to do a registry backup and defrag. It will say that it worked, and that it cleaned what it could, last time I did it it cleaned 9 out of 10 issues, the last one being unfixable, and it would say that defrag would be done on restart. So I restarted, and the black screen with the text saying "iolo systems inc. Registry defrag about to being." then a countdown, press esc to abort. I waited, and then it said please wait, and then it just didn't do the defrag and instead went on to the login screen. I don't know why. It does this every time i start my comp, and pressing esc to abort didn't stop it from happening subsequent times, nor did doing another registry defrag from sys mech. Does anyone know why?
