[Definitions Update issue]

Firefox, thanks very much for examining my files.

My mbam database definition update problem might have been caused by two missing Norton AntiVirus registry entries for file extensions. I reinstated them from a Ccleaner archive of unused file extensions, and now mbam updates work. I'm not sure the reg keys were the cause, beause I can't easily remove the keys again (in an attempt to reproduce the problem). It seems odd that the keys would have caused the errors you listed in your posting, but maybe they are part of Norton's internet protections.

I'll just stick with the current state unless the problem appears again.

Thanks again for your help.

Here are the 3 txt files generated by mbam-check & dds, as well as the last 3 mbam scan logs. It looks like a lot to sort through. Thanks for any help you can provide.

[Definitions Update issue]

I have had the same problem throughout today. Win7, IE8, Norton Antivirus, Comodo Firewall.

[Manual update "Looking for malwarebytes.org"]

"You have the latest database version" was the only response I got for a week when I attempted to update. However, the Listed Update Date, Database Version, and Fingerprints loaded never changed.

Removing rules.ref resulted in a message that the file was missing and an offer to download it. But the same file version that had been deleted was written back in, but with today's date.

It turned out that Internet Explorer was set to work offline. I'm posting because this appears to be a slightly different symptom of this IE setting than was so very nicely handled by the previous posts on "MBAM draws it's connection settings from IE" and the application of this principle to the Work Offline setting in IE.

Although I never use IE (and generally prohibit it from outbound communication), now I'll pay more attention to its settings.

Thanks VERY much for great information.
