When I tried to use 'System Restore' this is what I got on screen...'.Your System Restore has been turned off by group policy'. When I looked through our Forum someone gave me a different way to find System Restore I got it on screen but I couldn't click a date or click to change the month. The curser would highlight but wouldn't activate. Can anyone help me please. Regards, Ericus02.

Well, here's a possible solution: System Restore Group Policy restrictions

But this is also a possible indication of malware infestation so I would urge you to run a full anti-malware scan too.
