Yesterday I started having issue when I turned my computer on i could click anything on my desktop thinking it was my mouse I used my old mouse which I know worked fine, now I believe it may be a virus of some sort as I have to alt+ctrl+del and bring task manger up then I'm able to clicking on icons etc and it I minimize a program it happens again and can't click on anything.
Anyone else experienced this before? doing my head in having to alt+ctrl+del every minute
Edit: Using Windows 8 64bit, Done spybot scan and a sfc scan
