I was a little bit afraid installing iantivirus (1.2) into my macbook pro. But there is no fan issue as posted below. It is easy to configure and does its job fast and reliable. Much faster and easier to configure than intego virusbarrier i had before and uncomparable easier to handle than ClamXAV that is also a nightmare to install. So iantivirus is just perfect. Why can't everybody make such programs?
