MacBook got EXTREMELY slow the last few days

[POWERCOM]

1 week ago my MacBook was working perfect everythign worked fast. But since a few days my MacBook is SOOO EXTREMELY slow. I can't believe it.

I run Mac OS X 10.5.3. I didn't really installed anything on my Macbook so why is it so slow?

Maybe I have a virus?

Try restarting.
Try repairing permissions (with disk utility).

You mentioned that you haven't installed anything -- what about downloading? If you have been filling up your hard drive, that could cause the sudden slowdown. How much drive space do you have left? I've seen recommendations that you should always leave 10% of your overall HD space free.

If it's none of those, you'll have to be more specific. Specs of your machine, the software you're running when slowdowns occur, etc. It could be that you're trying to do too many things at once, in which case extra RAM might be the solution.

perhaps there is an application running in the background that failed to quit properly.

Does it feel really warm?

Just try rebooting it though, that will most likely fix it. If that doesnt open activity monitor and see if anything looks unusual.
