How to solve Java problems involving playing videos on firefox. Please see the details of this question.

Question

When I play videos (YouTube, Novamov, Videobb, etc...) I get a message from Java saying: " video format unidentified/unknown" and the video's picture start stopping and playing (frame by frame) while voice has no problem. What should I do? I've already reinstalled Java on my laptop but that didn't solve the problem. Thanks a lot!!!

Do a MALWARE check with Malware Scanning programs. You need to scan with all programs because each program detects different malware. Make sure that you UPDATE each program to get the latest version of their databases before doing a scan.
