I just wanted to comment on protection for Linux. Linux is not bulletproof. But, it is much more secure, of course. Linux operating systems have a team behind them that continually work to release security and software updates, as Linux is not vulnerability free. A particularly intelligent user will know that security updates for Linux are just as critical as they are for Windows. The antivirus/antimalware for Linux users, that are currently available (Avira, AVG, avast!, F-Prot, Kaspersky, BitDefender, Trend Micro, McAfee, F-Secure, ESET, Symantec, Panda, Dr. Web, Sophos, etc.) are mainly for business workstations and personal users that need the feeling of being secure. When used in personal situations, it is more for the beginner user that is not aware of security updating. The need for an antivirus is rather slim for Linux systems. I could imagine a personal user wanting an antivirus to scan documents, pictures, movies, etc. that came from a Windows machine. Also, if any user has a fad to be into social sites, particularly ones that contain social engineering attacks, they too should have an antivirus for Linux. Linux machines are vulnerable to most social engineering attacks.
