Virgin Pcguard anti-virus my work round may help you
When I run Ccleaner?s registry bit with all options selected, I get this as requiring a fix:-
?Obsolete software key Antivirus HKLM\Software\Antivirus?
If I allow Ccleaner to delete it on the next reboot Virgin?s Pcgard anti-virus bit does not work and the whole program has to be reinstalled.
I now run Ccleaner and uncheck the box against this line and everything is ok.
Running Windows XP Home Ccleaner version 2.19.889
Hope this helps
