What is the PF bar in the task manager, and why is it so high?

2 weeks ago this bar was at 110mb and would never go over 130, and now it its REALLy high, right now its at 250. Why is it so high now? I have no programs runnin in the background, no spyware, no viruses. I guess a better question would be what does PF stand for?

The ‘PF Usage’ graph shows the amount of the ‘Page File’ or ‘Virtual Memory’ (also commonly referred to as the ‘Swap File’) that is in use by Windows. Windows uses empty hard disk space as additional memory when it runs out of active memory space known as RAM (Random Access Memory).

Ok, then why has it gone up so freakin much. Windows always never went over 130mb, and that was wen i was using alot of programs. Now i dont have anything running in the background and its 170mb idle.
