Ok. I reformated whole computer using a Windows XP w/ SP2 integrated cd. I reinstalled everything. While I was using the computer certain things I do would make the computer totally freeze for a good 5-10 seconds. I can still move the mouse but everything else would not be clickable. I was able to reproduce this everytime by doing the following: 1.) Reset the computer. 2.) Open up My computer and go to a folder with alot of files and folders. Right click on the window. This causes this freezing to happen. I checked the task manager to see what was operating last when it happened. I found out the problem is with McAfee VirusScan On-Access Scan. It is the program that scans files as it is ran by the computer. I uninstall it and everything works smoothly. I reinstall it and the problem comes back. I disable it and everything runs smoothly. Enable it and the problem comes back. I did not have this problem before Service Pack 2. I am assuming the problem is with the Windows Security Center's Virus Protection. It keeps tabs on the virus scanner to make sure it is operating and it hangs up the computer.
