Weird problem with mouse clicking...

[-TC-]

Recently, when using the computer, my mouse seems to "unfocus" from what it was focused on. Meaning when using google chrome, I will notice the scroll will stop, and when I click on the google chrome window, it highlights again. (Like it would if I clicked on another window, then clicked back to the internet) It happens quite frequently, like every minute too. Also when playing games fullscreen, it will minimize to desktop.

Any ideas? Driving me crazy!

malware?

Stuck keys on the keyboard can do this, but I'd definitely scan for malware.
