I had been noticing that my Mac laptop had been running slow ever since I installed VirusScan (McAfee).   The real pain came when I found out that I had to use Firefox when using my blogging software WordPress.   My favorite web browser, Safari, would not work correctly with WordPress.  But here is the pain. Firefox would take forever to load, I mean at least three minutes or longer.   I decided to go into Virex and play with a setting or two. I opened up the Virus Scan application and chose to look at the Preferences.

Right away I chose to turn off “On Access Scanning”.   Then I opened up Firefox.  Pow!!  The application loaded fast!   I believe the problem was solved.
