I found a strange virus-like behaviour on my PC running Windows 7. I'm not able to type properly with my keyboard. Sometimes it won't respond, and some other times it adds characters indefinitely to the typing area. When I click on the desktop, it creates new folders. When I press Ctrl + N on a browser windows, it opens an unlimited number of windows.

I tried with Kaspersky and ESET antivirus trial versions, but I couldn't find any virus.

I don't always get this behaviour, but perhaps 50% of the time...

Hi, you may want to post this on - this isn't the place for this question. – Erik Mar 7 '10 at 9:20

It sounds like a hardware problem to me. I'd be keen to try another keyboard before hunting for viruses.

Even though it happens on clicks as well, I'd still try another keyboard; reboot after you try a new one though. – Jeff F. Jun 15 '12 at 17:52

but When i click on the desktop it creates new folders for each mouse click. It happened once. Anyway i'll try with another keyborad.. and the keyboard is just 1 month old.
