Using CCleaner for several versions without (known to me) problems.
Now moved to Windows 7 and Microsoft's Security Essentials. First scan produced warning of "High" threat from Win32/RegCure, and recommendation for "Cleaning"(?).
Security Essentials seems not to allow for copying details report (to reproduce here). However, all of the details involve CCleaner files held in NON-Operating (Utilities collection) or archived -- Windows.old (?), OLD DOCS -- folders.
Is RegCure actually used by CCleaner? Is there any kind of problem here?
