I uninstalled a program from my computer and the computer needed a restart to complete the operation.On booting up again I got the following message on screen:-"Your System Clock appears to have been set back. Please correct your System Clock before trying to run this computer.If your clock is correct contact AutoUpdate Support for instructions on correcting this error. (report Code CCB-F)" On checking the system clock I found the computer had made a System Restore point dated 25th December 2009. One month in advance. I then reset the clock to the correct date and time. Each time I fire up the computer I get the same dreaded message to reset the clock..The battery in the CMOS is new by the way

I have trawled thro my computer and found it to be a piece of software installed called "SpywareBlaster" which automatically updates daily.Uninstalled the offending programe now back to normal.Uninstalled all 'System Restore' points so wiped the slate clean.
