DJBone, thank you for your reply.
AVAST Software a.s. is currently blocking access to port 80 (that effectively means websites and updates of avast! software) of its servers from following countries: Iran, Sudan, Cuba, Syria, North Korea and Burma/Myanmar. AVAST Software a.s. [and its subsidiaries/sister companies] must not provide any services in these countries because of policies and regulations that are applicable to AVAST Software a.s.
Blog and forum are available, because we hope they are information source/personal communication service and because of this they have exclusion from these regulations.
I am in Spain. I am not in Iran, Cuba, North Korea etc. Is Spain blocked as well? If yes, why there is no official information about it?
I am very tired, nervous and angry. 2 years ago I had a trojan and a backdoor installed in my PC but Avast didn't report any problems. Now I spent almost 24 hours trying to find out why I can not update Avast and why I can not access Avast website. I have scanned my computer with all possible antivirus software - Kaspersky, Malwarebytes, Panda, Spybot S&D. No problems found, but I still can not update Avast and I can not access Avast website.
So many problems with Avast. Some time ago it reported all websites as infected:
http://forum.avast.com/index.php?topic=75982.msg628477#msg628477Then Avast reported that their own updates are infected:
http://forum.avast.com/index.php?topic=93599.msg745018#msg745018I am tired stress and of lack of official information.
If it's a similar case and updates and Avast website doesn't work because Avast have blocked something, tomorrow I delete Avast and install another antivirus software.
