Avast cannot update latest virus definitions?
« on: December 29, 2015, 09:53:33 PM »
So my Avast suddenly gave me notification of outdated virus definitions, even though I've always kept automatic updates enabled. I went to settings -> update and tried to update them and current definition version on my computer seems to be 151229-1. When I try to update, it seems to fail as version number doesn't change giving this:

Last encountered error: Invalid file signature. Setup will terminate.

Is this a problem with my computer or probably Avast update download itself?

EDIT: oh, someone else made topic about this issue just before me  :o

Several posts all over the forum about this already, so no need to start a new

No, your version (at the moment of posting) was 20151229-2 as it clearly says in the screenshot.
That was the latest version at the moment of posting.

EDIT:
Oops, that image is from Bob ::)
