I'm having two problems with my Vista pc, I don't know whether they're related or two seperate issues: (1) The Internet Explorer information bar at the bottom right of my screen says that protected mode is off. When I double-click it to change security settings everything looks normal and "enable protected mode" box is ticked on. (2) Secondly, after start-up, Windows security centre tells me that there no Windows security is in place. When I go to Windows Security Centre I'm told that the "Security Centre service is turned off" even though the "four security essentials" are turned on: Update, firewall, defender, internet options. When I click on the "Turn on now" button I am told that "the security service can't be started". Heres the currrent security programs I have in place for those who require such info: AVG Free Anti-Virus, AVG Free Anti-Spyware and Adware, Hijackthis, Spybot Search & Destroy, Zone Alarm and AVG Free Rootkit. Would anyone who has advice on how to remidy the above problems please reply asap as I'm not sure whether I should even be online. Thanks. I'm sure most people know what I'm on about when I mention the "Protected mode: on/off" toolbar. Below is the Windows Security problem to be more specific.
