Query: Regret installing Mcafee

I uninstalled Norton and installed Mcafee Security Centre as I read many reviews in various PC magazines giving the product a good review. I wish I had stayed with Norton. Mcafee is extremely slow and freezes my MS Outlook everytime Outlook performs a send/receive which in my case is every 2 minutes. I send receive about 1000 emails a month, and frankly Mcafee is slowing my business down by freezing Outlook every 2 minutes. I am going to uninstall and go back to Norton.
