If someone coded a virus and sent you it, even if you had an updated antivirus, it's unlikely it would be detected
Don't most antivirus programs have a function that blocks virus-like activity, from ANY virus-like code?
Some AV programs have "Script Blocking" which detect virus like activity from scripts or any other code, even if it is brand new and not found by AV companies yet.
For example, when the "virus" changes your MSN nickname without your knowledge, you would be alerted that a script is trying to write a new registry key, or edit a key.
