Thread: IE8 won't install McAfee Site Advisor

After installing McAfee Site Advisor, it is "grayed out" in the toolbar settings window of IE8; therefore I can't check it to turn it on. If the new
"Safety Filter" in IE8 tools menu is Microsoft's answer to replace Site Advisor, it's a poor substitute. Site advisor turns yellow or red when encountering a suspicious web site. Safety Filter requires that the user determine if they find a suspicious website, then they Ask Microsoft if it's OK. Site Advisor is far superior.

Any suggestions to get it to work in IE8?

I also upgraded to IE8 from 7, site advisor did the similar thing. I did this:
clicked on window help menu on IE
in search box type "resetting IE8 (or 7 whichever your case)
scroll down until you perceive choice for reset automatically
Click Microsoft FIX IT
download file from Microsoft
click run
When window pops up- click reset IE settings reset
close IE
when you re open IE it will request you McAfee Site Advisor turn on box already checked for addons (this enables site advisor in IE8 again)
click yes
After this, site advisor works great again. This will surely help you out.
