Avast Keeps Blocking Webpages At Trusted Sites

Avast keeps blocking webpages at Home Depot, New Egg, ect. The pop up alert states something about a certificate not being valid or up to date. How do I prevent this frustration? Shutting off the antivirus temporarily doesn’t work as the site is already blocked. This prevents you from being able to buying anything.

Go to Settings > active protection > webshield > Customize and un-check https scanning.

There is no need for that Tangy.

The solution is to update to avast version 2016.
In version 2016 the https scanning has been changed a lot.

Thanks. Unticking the box did the trick!
