Your online connection is also your Achilles' heel, allowing rapid infection of hostile code into your PC. Only Achilles'Shield has what it takes to defend against both the known and - more importantly - unknown attacks that threaten your security. Achilles'Shield stops Trojans, viruses and worms by their distinct behavior and not by signature code, providing protection between traditional anti-virus software updates. While signature-based scanners are effective at identifying known threats, new and previously unidentified viruses are constantly being released In-The-Wild. Based on patented InDefense technology, Achilles'Shield provides unparalleled defense against these unknown malicious code attacks.
