TLS 1.0 on Internet Explorer 8 will not stay selected after one or two restarts of Explorer.

I recently purchased a new laptop with Windows 7 and Internet Explorer 8.  One of the things I use it for is to access my work email remotely.  To do this, I have to select TLS 1.0 in the Advanced tab under internet options.  Every time I select this, though, after one or two restarts of Explorer, I can't log on to my work email.  When I check the settings, somehow TLS 1.0 has become unselected.  This has happened at least a dozen times.

I have tried turning off all Virus Scan and Fire Wall software to see if that was blocking the setting changes and it wasn't.  I'm at a loss.

Mike,

 This seems to be an error with McAfee's software and I recently confirmed this solution (by pigglety ) on the McAfee forums:

 "To work around the issue, I have been applying a local group policy to my home PCs. If you have a Professional, Ultimate, etc. edition of Windows, the policy can be applied using the Local Group Policy editor.
1.        Run gpedit.msc.
2.        Go to Computer Configuration > Administrative Templates > Windows Components > Internet Explorer > Internet Control Panel > Advanced Page.
3.        Set "Turn off Encryption Support" to Enabled and select the Secure Protocol combinations that you want."

There was indeed McAfee preinstalled when I bought the system.  My subscription is current with it.

McAfee applications are notorious for not upgrading (or uninstalling) cleanly. Try this McAfee three-step fix: http://service.mcafee.com/FAQDocument.aspx?id=TS100507
