PC utility and security vendor PC Tools introduced iAntiVirus, a Mac-specific anti-malware application.The software is designed to be configurable for the optimum balance between speed and thoroughness. It provides real-time protection, alerting users immediately when a suspicious file is detected and blocked. Detected files are placed in quarantine so the user can inspect and, if it's a false positive, restore them.

"The Mac has a solid reputation for remaining relatively threat-free," said PC Tools CEO Simon Clausen. "However, we are witnessing the use of low-level malware scripts to identify whether there is the potential to infect the Mac OS, as well as the opportunity for malware producers to obtain a significant return on investment."

iAntiVirus is a free download; full support and updates for a year will cost $29.95.Macworld
