Not able to download Virus Definitions - INTANGIBLE HOST !!

Hi,
I dont know why, but it’s now a week that I am not able to update virus definitions.
It has been always set automatic. It has worked. I haven’t changed anything on pc and antivirus, not with purpose at least …
It is trying to update the definitions but it comes out with a strange message, INTANGIBLE HOST. Actually mine is a Brazilian Portuguese version so the original message is Host Intangivel …
Help! :-
Many thanks
Dan

See if a repair solves it.
Control panel > software > add/remove > avast > choose repair

Hi,

Another option is to manually launch VPS updates. http://www.avast.com/en-eu/download-thank-you.php?product=VPS9&locale=en-eu
