Characteristics
When run, this file indicates that it is a MacCodec installer.

Rather than installing a real codec, it creates a scheduled task which changes the DNS server to point to a malicious site. This could be used to redirect a user to a phishing site or more malware.
Within Finder, the script and the folder it creates are not visible. In the console, the script can be found at the following location
- /Library/Internet Plug-Ins/plugins.settings
Symptoms
- Presence of the file plugins.settings
- Websites typed in by an infected user may be redirected to malicious sites
Method of Infection
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. This trojan is most commonly installed by going to a malicious site.
Removal
All Users:
Use current engine and DAT files for detection. Delete any file which contains this detection.
