Overview
-- Update March 31, 2009 ---
The McAfee DAT files have incorrectly identified clean .swf files as containing this exploit. This impacted Rosetta Stone language training software. This false detection was only seen with McAfee Antivirus products running the 5301 engine. McAfee DAT file version 5570 has resolved this false detection.
------
This is a trojan detection. Unlike viruses, trojans do not self-replicate. They are spread manually, often under the premise that they are beneficial or wanted. The most common installation methods involve system or security exploitation, and unsuspecting users manually executing unknown programs. Distribution channels include email, malicious or hacked web pages, Internet Relay Chat (IRC), peer-to-peer networks, etc.
