Anti-virus software maker Sophos -- who recently introduced a free Mac Home Edition of their anti-malware program -- have gathered the statistics generated by their 150,000-strong Mac user base to compile a snapshot report on threats facing the platform. While the results tacitly admit the lack of actual Mac viruses and the low incidence of other Mac-specific malware, the company says the risk of Mac-specific or platform-independent non-virus malware -- and the need for detection software -- is growing.
