I have SpySweeper, Spybot, Windows Registry Repair, Ad-Aware SE, Microsoft AntiSpyware, McAfee Virus Scan.
Over the past month, for no apparent reason, I have been unable to ADD or DELETE sites in my TRUSTED SITES zone.
If I try to DELETE a site, it just reappears after I click OK.
If I try to ADD a site, the following message appears;
X Sites added to this zone must use the https:// prefix.
This prefix assures a secure connection.
