What is the best protection policy for my computer?
There is no “best” anti-virus policy. In particular, there is no program that can magically protect you against all viruses. But you can design an anti-virus protection strategy based on multiple layers of defense. There are three main kinds of anti-viral software, plus several other means of protection (such as hardware write-protect methods). 1) GENERIC MONITORING programs. These try to prevent viral activity before it happens, such as attempts to write to another executable, reformat the disk, etc. 2) SCANNERS. Most look for known virus strings (byte sequences which occur in known viruses, but hopefully not in legitimate software) or patterns, but a few use heuristic techniques to recognize viral code. A scanner may be designed to examine specified disks or files on demand, or it may be resident, examining each program which is about to be executed. Most scanners also include virus removers. Examples: FindViru in Dr Solomon’s Anti-Virus Toolkit, FRISK’s F-Prot, McAfee’s VIRUSCAN (al
