I just bought a program called Performance Pro that blocks online viruses, cleans up the hard drive to DOD specs, and speeds up the loading of web pages by blocking popup and inpage ads. Its free to try for two hours from here, no activation key required for free test drive:


I find the virus blocker invaluable as I used to get bombarded with spyware/adware etc. No longer. The program has an auto-updater for various enhancements.
