Youtube videos ain't playing....?

[Andrew]

You need to add some additional Plug-in to run a video in youtube some cases youtube itself ask to install Adobe flash player if like kind of thing is mentioned you need to install Adode flash player. In some cases virus must have affected u already said you have install Anti-Virus and checked too but anyhow try to uninstall the Antivirus and again install it may fix you problem issues.

Try to download the best Anti-Virus product if the above solution doesn't work for you when i face the same problem i tried by using best anti-virus product Comodo Antivirus it fixed my problem now i can watch any videos in you tube without any problem.
