AVG is hoping that greater awareness of the universal nature of web-based threats will attract Mac users as it targets that operating system for the first time.
Traditionally Mac has been perceived as a secure platform with the virus threats being aimed at Microsoft platforms. But with the web being used as the route rather than the OS there are problems for all computer users.
"Mac users have traditionally been less vulnerable to virus threats and attacks because of their lower market share, but that is quickly changing and no operating system is immune," said J Smith, CEO at AVG Technologies.
The security vendor has launched its LinkScanner product for Mac that warns users if they are about to click onto sites that contain threats.
AVG is using the same model it has established in the PC space making the software free hoping that users will upgrade to more sophisticated products that are charged for.
