I am setting up a P-III for my daughter. She already has an AOL account. I purchased McAfee's latest AntiVirus program for installation on her computer. However, I see that AOL offers free AntiVirus by McAfee. Other than the fact that the AOL version is free, what, if any, are the differences between the 2? A friend who has the AOL version told me that it is very disk intensive. Does the AOL version include AOL related items which cause it to be more taxing on the computer's CPU?
