After purchase the full product did not behave as the trial and has (sometimes) offered an ABORT button
after a single scan rather than REPAIR. I await a reply from the Support dept. for RegistryFix.com.
In addition it only retains ONE backup set and not several to choose from, so if you take the trouble to scan in stages as I did the first backips are overwritten by later ones.
The result is I cannot restore changes sufficiently and, for whatever reason, the
software impact has made McAfee Antivirus/Security Center unusable or even
repairable. I have had to strip the machine and start over (with new antivirus).
