AVAST blocking www.vodafone.co.uk

When trying to access www.vodafone.co.uk it just times out regardless if using Chrome, Internet Explorer, Firefox or Edge.

If I disable Avast I can connect no problem at all with all browsers.

For some reason Avast appears to be blocking Vodafone and I would like a better solution that having to disable my antivirus to visit their site.

What shield is causing the problem ?

Not being blocked here and is reasonably quick to load, see my signature for system spec.

Windows 10, creater update
Avast free 17.4.2294 - 17.4.3480.0
VPS 20170525-0
Opera 45.0.2552.812 (PGO)

Site is blocked without a warning/message from avast.

Windows 10, creater update
Avast Internet Security 17.4.2294 - 17.4.3482.0
VPS 20170525-2
Google Chrome

Site is working fine here without any issues.

Just tried it on my win10 Home 64bit, firefox and avast free again with no problem.

I do notice that it has a Cookie policy initially at the top of the screen, which I closed. I manage cookies with CookieMonster add-on and firefox settings to block 3rd party cookies.

Seems like a vps (and micro fix?) update has solved the problem.

Could be.

Cookie policy attached below: You mean this?

Yes, that is what I meant.

With CookieMonster I allow session cookies only for the site and when firefox closes, my firefox removes these cookies when it closes. I don’t know if anyone with a more strict policy on cookies, not allowing them at all would result the sites not being displayed. That just sounds too severe action by a website though.
