Yep, it's McAfee SiteAdvisor that I never asked for.
But now the problem is that it's impossible to get rid of. Sites claim it should be in the installed programs list but it isn't.
It is also suggested to start removing McAfee and then it should give you the option to only remove siteadvisor, but it doesn't.
And I also can't remove it within IE (tools-addons etc).
Unfortunately my employer arranges/pays for the virusscanner so I can't just uninstall everything. Is there a way to remove that !@#$ McAfee SiteAdvisor?

BTW I am tempted to just throw away the SiteAdvisor folder in C:\programs etc. Would that work?
