Hi, this might sound stupid, but but whenever I press any Lock key (such as Caps Lock, Num Lock, etc.) my computer pops out whatever I'm doing kind of as if I had alt-tabbed. For example, if I were writing an e-mail, and I pressed Caps Lock, I would have to click on the place where I was typing in order to continue my e-mail. I was wondering if this is an adware/malware problem and how should I fix it?
