VAC Codec
VAC Codec is a fake multimedia player. VAC Codec comes attached with a Trojan virus, and to trick the user into launching VAC Codec, a pop-up notification is received prompting the user to download VAC Codec in order to view a certain adult video content. Once active, this trojan may download additional malware onto the compromised machine, modify system files or open the computer up to remote access by outside attackers.
