Hi Shelf Life.

I have switched System Restore off and on, with appropriate reboots, then created a "post-cleaning" Restore Point.

Many thanks for your invaluable guidance, without which I would still be enduring the frustrations, vexations and worry of the Smitfraud virus on my computer. May all your help to afflisted victims of computer infections be equally effective and equally appreciated.

With my sincere thanks,

BolderBiker
