gjbnh,
I really would not trust this program whatsoever.
I just ran the Pro version on my Windows 7 machine. I have 84 system optimazations found and 5228 Security Defense problems found.
These Security Defense is a total joke. It just lists the various types of malware that exist out in the wild. It's supposedly giving you protection from these. If you have a good anti-virus program, spyware detector and personal firewall, there is no need for this.Also, it detected a dll of mine as a porn pop up. This is absolutely false and if I was to remove it I would break the program and it would not start.
I'd go so far as to state if you fixed all these so-called problems Windows would not even boot.
I never belied in these...
