Sorry, but I don't use the tool so I'll suggest you visit the new McAfee SiteAdvisor forum at the link below. Here is a link which looks like it should help you accomplish your task:
If that doesn't get it done, then try searching the forum for your answer or post a new question.
Hope this helps.
Is it possible to use the McAfee site adviser on internet explorer 8, without the toolbar? just the BHO ratings search setting option turned on? and have it stay that way everytime I close & re-open a new ie browser window? If all that is a possibility, any suggestions on how to go about making the proper accommodation settings to have it function like the way I just described?
