Well I ran all superantispyware,ADW cleaner,Spybot,Also ran malwarebytes I have the pro version of that.
Went into programs installed I used the iobit uninstaller and deleted all latest installed programs.
I did down load a few days ago codecs for windows media player that may have been the culprit,I have been so careful when installing software watching out for sneaky addons this one must have been clever and slipped through the net.
Update at 06/01/2013 0850hrs,After all scans etc all looks well its gone.
Many thanks to all once again.
