I just downloaded Firefox with a refresh. Norton advised me that the download of gmpopenh264.dll is safe. Google search says remove, it's a virus. Please advise

Posted

Hello, my refreshed copy of Firefox I just downloaded is working just fine. However, my Norton anti-virus notified me just now that 2 downloads of gmpopenh264.dll were safe, but I did a Google search on that data library and there are numerous different postings on blogs advising to delete it due to it being a virus or is infected with a virus. Will someone with Mozilla please advise on what it is and if there have been problems...I downloaded my copy of Firefox directly from the Mozilla.org website. Thanks

Hello ryfumo,

Totally understandable that you are confused by all those mixed Google search results .....

But it is the OpenH264 plugin, which is part of Firefox to provide full compatibility with WebRTC.

Norton has been known to do false positives with Firefox, Thunderbird, and SeaMonkey related files over the years though.
