Query: Horrible!!

I have been a Mcafee user for the past five years. Decided to purchase this product based on past experience. Once I installed it, the problems began. Email took at least 10 min. to open up and my computer's performance became nonexistant. Uninstalled it and everything was normal again. Reinstalled it - same problems. Decided to go to McAfee's website to see if there was a patch or something. Nothing at first and then went further into the online forums. Then I realized that myself and about 5,000 other people are having this same problem right now. Check it out for yourself. Trust me - there's better ways to waste 50 bucks.
