The unique thing with F-Prot is that is has a DOS based scanning engine included. This can be helpful if you become infected with a virus that leaves Windows inoperable. However, there is no scripting protection, registry monitoring, Instant Messaging, or Peer-To-Peer application protection. Also, this is the only product that we reviewed that has not been ICSA certified. F-Prot does, however, hold the VB100% certification. If you are only concerned about speed and basic file-based virus protection , this may be the product for you.
