Anti-virus for a Mac: To use or not to use.
Every time a new virus or malware is found, Apple usually provides a solution in the form of a OS update or a security update. If the Mac OS is being regularly updated, there is no need of an antivirus. I would prefer Apple’s updates any day over installing an antivirus, which, besides slowing down the system, creates more security holes and also consumes bandwidth. I don’t use an anti-virus.
