Brief Description 

    

ZCodec is an adware program that passes itself off as a video codec.

It accesses an IP address on the Internet in order to download and run a certain file at random. This file can be of any nature. For example, ZCodec could download the Trojan Ruins.MB, which uses rootkit techniques in order to hide itself. Or, it could install an online casino.

ZCodec also changes the DNS configuration and monitors if the user accesses any of several adult websites.

ZCodec can be voluntarily downloaded from a certain website.

Visible Symptoms 

    

ZCodec is difficult to recognize, as it does not display any messages or warnings that indicate it has reached the computer.
