I have recently signed up to ancestry.co.uk. Every time I access the site I get a yellow information bar in IE9 stating "AnAdd-on for this web site failed to run" and there is a blank area where an advert should be. I also see that there is a blank advert box in my Virgin Media Homepage. I have discovered that SpywareBlaster is causing the problem and by disabling Restricted Sites protection the problem is solved. The question is which entry is blocking the Add-on and stopping the adverts. It has been suggested that I should enable each entry one at a time to find the problem but there are thousands of entries. Does anyone have any suggestions please.
