Time Keeps resetting

Every few days or so, the computer clock resets itself, only the hour though, the minutes are always correct…Possible virus?

Could be but sounds like CMOS battery is dead. On the board inside your tower, you'll see the battery. Its about the size of quarter and silver. Get the numbers off of it (without removing it) and go get you a new one. Before you replace it, might not hurt to first go into BIOS and copy down your settings.
