unable to connect to server

[How67ard]

still have not got anywhere and have downloaded the latest to one pc but still the same error unable to contact server. This is the same even without a firewall running. I am running ms security essentials on my main pc now but miss the old notification that the virus prog has been updated as with avast 4.8.

Same here.  This computer can connect to Avast.com.  My other computer cannot.  Going to try and remove 5.0 with the removal program supplied by Avast!  Then I will try to reconnect.  And/or, since I saved the 5.0 installation program on a Smart Disk, I will try to reinstall.

Been hoping that the technicians here can help with this problem.

Firewall and hosts file are, generally, the actors of this play... avast should be able to update by itself, something is blocking it.

I had the same problem recently. I was able to get my pc to connect after going into setting/updates/proxy setting and selecting direct connect no proxy. Of course if you use a proxy this may not work for you.

Well responding to a topic which started almost a year ago on a different avast version isn't advisable.

There would be many other more recent topics which offer the same advice if the current version 5.1.889.
