Slow laptop - please read?

My laptop was working fine til this week after I copied some cd's onto it to put on my mp3 player. I think I deleted the versions and emptied my recycle bin of them after I got them on my mp3 player but now my system in general is running slow. My internet is running fine and quick it's just things like startup, opening new windows, accessing menus which is slow. I've ran a full scan and there are no viruses, spyware etc, I've tried defrag and it says I don't need to, I tried system restore to 2 weeks ago and it says no systems were changed and I have plenty of free memory. Any suggestions? I use Norton Antivirus but see it isn't highly regarded...is there another spyware detector I could use as well as it? Also after reading some q %26 a's on here could it be just that my fan needs cleaned?

Yes it always a good idea to clean your fan...... But i am sure the problem is programs running in the back ground so if i was you i would remove the program you used to copy the CD with and find a new copy program.... or remove your from start-up.... Check for the icon in the bottom right corner of windows it should be the program you copy with and right click on it and close it.... It kind of like Yahoo Messenger running in the back ground when you start your computer, your computer takes time to load because its signs into Yahoo from the start-up, so the same for some down load music programs, you can turn this feature off....
