Somebody please help me with my iMac......?

I cannot watch youtube videos anymore. It says something about a plug in blocking. I think it's the google earth plug in but dont know how to fix this problem! PLEASE HELP!

What on earth has Google Earth go to do with playing videos? Stupid idea. Since the Imac is an Apple machine it is far more likely to be a Flash player or one of the html5 video player extensions That is blocked by Apple security as it does not have their certification. This is becoming a serious problem for all Mac users as they are so determined to make EVERYONE use apple created software as the basis for anything Internet related, so they are not getting support or giving any help to developers.

Upgrade to OS 10.6 or later. Then install the new Flash Player. Apple has blocked the old versions for security.

OTHER ANSWER :
...has created a concept far from reality. Apple blocks older Flash plug-ins, because Adobe has not made them secure. If the system gets malware through an insecure Adobe plug-in, do you think PC geeks are gonna be shouting about Adobe? No way. They will be shouting "LOOK!!! MACS GET VIRUSES!!! DON'T BUY THEM!!!"
