I wouldn't use Norton as well. I have friends that have nothing but trouble with it. Then My sister and brother in law swear by it. Maybe the answer is if it works for you then why change. I use the following and I run a scan once every two weeks.
Ad-Ware Se
Ewido
Spybot
AVG
I just finished running the Trend Micro Housecall and I think I will in the future as well. It didn't find any problems though.

Off the subject a little. Someone told me that I should use Mozilla FireFox as my search engine and to drop Internet Explorer. The reason being that FireFox is safer. Well. I used it for about a week then decided that I wanted to go back to Internet Explorer. So I deleted all of the FireFox files and now I have a problem.
   
When I receive an e-mail and it has a internet site to go to in the message area, I cannot open it. I tried and tried and it won't work. So just by chance I downloaded FireFox again and presto. No problem. So now I have Firefox in my hard drive taking up space and I'm not happy.
Thanks for the listen and enjoy your thread Mark
