What would cause this kind of problem with computer memory?

I have a MacBook Pro with an Intel in it and I admit that I have dl’ed quite a few torrents. But I’ve scanned my computer a bunch of times with MacScan and once with ProtectMac AntiVirus and neither one of them came out with a single bit of spyware or tracking cookies (though they are demos and I don’t know if that matters much). I also cleared out almost (like 99%) of my documents and pictures off my computer and onto an external hard drive. I even got ride of some programs I never used and some music that I don’t listen to and have backed up on my ipod anyway. Can anybody suggest something useful?
It’s just that I have like 76 gb of memory on my Mac and I only have 14gb of free space after I delete and move almost everything.

You seem to be confused about the difference between memory and storage space. NO mac in the entire world has 76GB of memory,(Random Access Memory). This 76 number is your hard drive size. You have 14GB of available space. I am sure there is some sort of hard drive analysis software for mac that will let you see what is using all this space. Go and find one and use it.

Good luck.
