I've been having issues with SiteAdvisor blocking perfectly safe sites (recipe sites, reddit, etc) and it's really getting frustrating. I can't even find any sign of SiteAdvisor on my computer (other than when it blocks things). I'd love to change the settings or just remove it at this point but I can't find it. It's not listed under the programs on the start menu, it's not listed under "add/remove programs". Nothing. The only mcafee listings I have are:
McAfee Antivirus Plus
McAfee Security Scan Plus
This is a Dell computer that came with one of those already installed and then the other one got loaded when I purchased McAfee after the trial ran out.
SecurityScan Plus is merely a security checking tool that you must have downloaded as an optional extra with, for example, any Adobe product installation or update. You have to watch out for those 'extras', however it's easy to uninstall. It should be listed in your program list in Control Panel.
To disable SiteAdvisor simply go into your browser Tools > Add-ons and disable it. It will not work the next time you open the browser.
Or, you can uninstall just that part by clicking the McAfee SecurityCenter item in your Control Panel Program list and selecting uninstall. It should prompt if you just want to uninstall that component.
I counsel against that however as SiteAdvisor is a good safeguard against possibly dangerous websites and downloads and the warning can always be bypassed.
