it's pointless to make a backup anyway because you can download it from the web (I mean from their web site).
My Aunt is paranoid about system mechanic and runs it almost everyday on the "full" setting. Of course the reason her system is slow is because SMSystemAnalyzer.exe is constantly running as well as it's services.
And then there is of course the "random" corrupted of installations that occurs after running it's registry tools... But goodness no, it's not System mechanics fault- it must be a virus! I better run a full system scan again!
