How to Remove a Codec Virus

By David Harris

Media-Codec is a type of trojan horse, a type of malicious software that gets onto your computer disguised as a harmless file. Media-Codec files often gain access to your computer when you try to watch adult videos on the web, as they pretend to be required upgrades to a program like Windows Media Player. Trojans like Media-Codec are dangerous because they can contact other servers or computers and give sensitive information about your computer. Removing a Media-Codec trojan from your computer is multi-step process.

Tips & Warnings

  • Some Media-Codec files do not have obvious names. You can download a security program that identifies processes running on your computer and lets you know which are safe and which are malicious.
  • Make sure the Media-Codec file isn't running before you delete it. You can close it by hitting "CTRL+ALT+DEL" at the same time. Select "Task Manager" and then "Processes." If you see a Media-Codec file running, simply close it.
  • If you are unsure if a file is a Media-Codec, do not delete it until you found out what it is. Deleting files without knowing their use can cause serious problems to your computer.
