Ok this is starting to get really annoying. I do not understand why my computer is so slow. I have used Disk Clean Up and Disk Defragmenter after it was done scanning my computer it was still slow. I have used some programs to get rid of unnecessary files. The free programs I have used are Ccleaner and Glary Utilities it scanned my whole computer and it was still slow. Then I bought 2 programs that are called Registry Booster and Registry Fix 7, and these are not freeware, I scanned my whole computer and it was still slow. So then I started to suspect I had a virus, so I went out to buy ann anti-virus, it was called Avast Internet Security 2009. I had many viruses so then Avast took care of every single virus. But still my computer is slow what could possibly be the problem? I have many programs installed on my computer, and it was working fine and it was fast, then at some point my computer got slow, can someone PLEASE PLEASE HELP ME!

ok. so i did some looking around. and downloaded some programs. and so far i have tried avast antivirus, avira antivirus, and avg antivirus and have come up with no virus results. i have also tried some spyware programs and have not had any spyware threats on my comp. i have tried to use glary utilities to clean my registry and remove junk files . this makes it worse. i have used ccleaner and that did absolutely nothing. have defragged my system even tho it said it didnt need defragged. and have advanced windows care installed.

some people have told me that the problem with my computer is that i download and install too many programs and have too many things running in the background. i have since uninstalled a lot of programs and have had no improvement.

is there anything short of reinstalling the OS, that i can do with my computer to clean up junk files, or find what the problem is? right now it takes 5 min to open a new tab in firefox. and i have maxed at 3,000 page faults/s

I currently have ccleaner and Glary Utilities which are both freeware that I found. I am looking for a suite that will fix my registry, remove privacy info, remove temporary files, remove spyware, etc. I would like the best all in one program that is very useful, but as i stated, i prefer freeware and even better yet if its from a safe place like download.com or something like that (although all suggestions are accepted).
