OpenH264 (also known as OpenH264 Video Codec provided by Cisco Systems, Inc., OpenH264 Video Codec Provided by Cisco Systems, Inc. 1.1, H.264, Open Source H.264 Codec, OpenH264 virus) is a free legitimate browser add-on and extension primarily for the Mozilla Firefox Internet Browser, but can be used across multiple browsers. Users have complained to have found a browser helper object (BHO), add-on, and extension titled OpenH264 Video Codec installed onto their Microsoft Windows computers and attached to Google Chrome and Microsoft Internet Explorer without their consent. Furthermore, users have claimed that OpenH264 can be used to serve advertisements, including in-text advertisements and generic banners.
OpenH264 Video Codec was first introduced to Mozilla Firefox v33.0. The codec is used to enhance video quality on the internet. It may be pre-installed on several internet browsers, including Mozilla Firefox, but is not a necessary component and can be removed. Users may notice the add-on after updating Mozilla Firefox.
Some users have complained to have found OpenH264 Video Codec installed without their consent and have said that the application was being used to generate pop-up advertisements. After analysis it appears that OpenH264 Video Codec is not advertisement-supported, but malicious and questionable parties may replicate the title of the program for unspecified purposes. It should also be noted that in some cases disabling and removing the OpenH264 Video Codec add-on and extension can cause specific advertisements to stop appearing that are generated by third-party adware like Text Enhance.
