IE 8 Security TLS 1.0

On Win Vista Business (Dell XPS M1530) installed IE 8, Version
8.0.6001.18828. have some sites that require TLS 1.0 to be enabled
(checked), I check and all is good. I close and open the browser TLS 1.0 is
unchecked, so basically have to go in each time to enable. Is this a feature
or a problem?
Is there a fix for this?

If it's not caused by a GPO...

One or more options/settings in an ever-growing number of third-party
applications may be disallowing the changes from "sticking." These include
anti-spyware applications (e.g., Ad-aware's Ad-Watch, Spybot Tea Timer,
SpywareBlaster, SpySweeper, Spyware Doctor, CounterSpy, WinPatrol, etc),
anti-virus applications & security suites (Norton, McAfee, ESET/NOD32,
Kasperky, Trend Micro, etc.), and third-party firewalls (e.g., Zone Alarm,
etc.).

Note that temporarily disabling the application(s) or rebooting into Safe
Mode may not disable the application's system protections.
