Trend Micro's PC Cillin is the only antivirus I know of that offers telephone tech support. I like to know that if I have a problem, I can call someone who can help. I think you can get a three computer license for less than $20. Do a Google search for the one you want and find an on-line retailer. They are far less expensive than buying from the Trend Micro website.
