This doesn't have to be a Malware infection Tommy.
It may sound silly, but have you tried uninstalling and reinstalling the flash player?
Also try to allow it through whatever security you have installed, AV and Firewall. It could be that flash is being blocked!
Some resources which may help you tackle this in Firefox HEREHERE
you'll find how to handle the same issue in IE8 as well.
Let me know if this has helped!
