Hi there

Basically about 10-15 mins ago I was using my computer and browsing around the net, and after I closed the net window down, and I started updating my anti-virus I noticed that whenever I tried to click and drag a window, it would automatically scroll along my screen to the left-hand side. I also noticed that it wouldn't let me type or write text as it would just keep going back to the beginning automatically, and it also wouldn't let me select anything in my Windows interface, like it wouldn't let me end programs or whatever or click any buttons. I did a virus scan but it came up clear (I use Avira Free Anti-Virus) and I have just restarted my computer and everything seems to be fine again now.

Does anyone have any idea what was going wrong with my computer before, and if it's something I should worry about? (eg. viruses/hackers etc)

I also use Comodo Free Anti-Virus with all of the settings on maximum security or whatever it is and I keep my Anti-Virus up to date aswell.

Thanks for your help.

Problem could be the two anti virus programs conflicting with each other, pick one and get rid of the other. You can run multiple spyware programs, but not anti virus. By the way, AVG free is excellent.
