Dear Android Linux,
Any Linux user will have a ROFLMAO attack and instant brain aneurysm, if a Windows user tells him that Linux needs antivirus protection ! Ha ha ha ha ha LoL LOL !
Whew! … that was close
Any way, apparently the most obvious reason to have an antivirus protection on Linux is when you have or work in a mixed environment. Lets say, you have a Linux PC/Laptop/Netbook for the real life stuff and a Windows PC for gaming that are connected to each other for file sharing.
