I have had no problems and do NOT have the 'Claro toolbar' listed in 'IE8 tool\toolbars or showing on browser. I have NOT had my IE8 browser homepage hijacked. Nor do I *seem* to be showing any apparent other symptoms of Claro.toolbar. ie I do NOT have Claro/iSearch listed in either Programs folder or in Add/Remove Programs.

I checked the alerted CLSID {F80D4C14-AEDD-3BFA-BFCF-A0ECE95AD209}
in my Registry and found a ref. to MuvEnum software(browser ext. 'Last Closed Tab'). I do have this 'Last Closed Tab' browser extension from MuvEnum(v4.1.0) installed from 2-3 years prior. I have no problems with it.

For ref. here is the MuvEnum home-d/l page:

So is this a False Positive then?
