So my Avast suddenly gave me notification of outdated virus definitions, even though I’ve always kept automatic updates enabled.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
