[@CollectorOfMyst] - Probably not age and unless you've been bogging down your system with startup or backup programs, probably not the physical RAM either. Again, if you've installed and are running a bunch of programs in the background (or they have memory leaks due to poor programming), then that's probably it... if you aren't.. yeah, sounds like a virus. Chrome and Firefox do have memory leaks though, I believe (continuously uses more RAM the longer it's open and the more tabs open).
