After attempting to remove SiteAdvisor I still have the Checkmarks, X's, and ? marks indicating a site's safety rating next to all my links. The SiteAdvisor button in the tray of my browser is gone, but not the link to the site details link. I hoped after removing it (and even uninstalling and reinstalling FireFox) it would fix this problem, but it hasn't.. I just want to remove all traces of this program/add-on (for personal reasons, please don't ask). If anyone can offer any help i will be eager to receive it.
Did you reboot after removing SiteAdvisor from the Control Panel/Add or Remove panel? There is no specific removal tool for SiteAdvisor but there is for McAfee in general, assuming all versions are within the last 2 or 3 years.
1. Uninstall all McAfee programs through "Add or Remove Programs" in Windows "Control Panel".
3. Launch Windows Explorer and delete all McAfee files in "Program Files" but especially in "C:\Document and Settings\<user>\Application Data" and "C:\Document and Settings\All Users\Application Data". You have to set Windows Explorer to show all hidden files and folders (Tools > Folder Options > View tab). Just delete the McAfee folders even if they are empty in all the "Application Data" folders. Can be more than one! In Vista: C:\Program Files, C:\ProgramData and C:\Users\yourname\AppData\Roaming
4. Reboot and redownload/reinstall your McAfee products directly from your account at the McAfee web site.
