I have been reading about a new form of anti-virus program available free on the Internet

It is called SurfinGuard and is produced by Finjan at www.finjan.com

It is said to be a totally new type of security system as it is pro-active and will block or close down any program that tries to alter your computers files

My problem is that although I am interested in getting the best possible security as cheaply as possible I do not have the technical knowledge to assess this kind of product

What do you think? Is it a waste of space or something that I really should have?
