Computer trouble again

I'm off the air for a bit whilst I determine what to do about a computer that has developed a mind of its own. This one I'm using is not mine and seems quite friendly, but I can't use it that much. So I'm off to see a man who knows more about the devilish notions computers sometimes get. Currently mine is refusing to get out of bed despite several doses of virus remedies and hard drive corrective treatment. I'm told there is a cure. Hope he's got the right one!
