Antivirus Program

Hey Guys and Ladies, I'm like most people in the thoughts of not going on the WEB w/o virus protection. I am having a lot of trouble at this time trying to get my antivirus program to work right. It's been several days now in "working " with the company and just can't get it right. My Antivirus program is " etrust EZ Antivirus " Do any of you'all have an "antivirus " program that is RELIABLE ? My "program" expires in March 2006. Looking to change.. Appreciate your help. caveman
