SSL Broken Lock

We run an SSL site and use Avast.

Chrome is showing a broken lock on our site, with the text “This site uses weak security…”, “Chrome verifed that avast…”, “Your connection to Avast uses a moden cipher”.

I came to the site avast site to find a solution and lo and behold, even the Avast site was showing the same problem.
I’ve uploaded an image showing this.

Just installed the newest version of Avast. That had no effect.
Any help would be appreciated.

The problem is Chrome, not avast.

To say it simple :
They basically want every site to use a secured protocol, but don’t have Chrome correctly setup for “self signed” certificates.

Hi, we have started to use SHA-256 signatures and hashes in our Web/Mail Shield MITM certificates. However in the previous version, SHA-1 was used. In this case you probably still have our “old” SHA-1 root cert installed that need to be re-generated. Reinstalling avast should help in your case and is the easiest way to fix that, or, if that is not an option for you, let me know, I can instruct you how to force the certificate regeneration manually.

Will upgrading to the latest version also work ?

Lukor,

What do you mean by “Reinstall”? I click on the taskbar and clicked “Update” and then “Program”.
Is that what you mean by “Reinstall”?

How can I force Avast to accept self signed certificates.

By the way, what is a self signed certificate compare to a non self signed certificate?

Thanks!

David

Which Avast…? (Free/Pro/IS/Premier)

You can try deleting history in Chrome. Chrome caches certificate info and may not show the currently received certificate.

Also check the file aswStreamFilter.dll, if it belongs to the current version, which is 11.1.2253 (Properties/Details in Windows Explorer).

Avast Free.

Thanks for the suggestions.

Just out of interest…

How does the lock appear to you on this page:
