Has anyone else had the same problem? I downloaded Avast Home Edition 4.8 from the Avast website yesterday and today, but after installation the resident protection won’t come on. Upon a little investigation I found out the version downloaded is wrong at the source! I think it downloaded the Pro version instead, even though I’m at the home edition download page.
From the Avast home edition download page at http://www.avast.com/eng/download-avast-home.html, through link titled [avast! 4 Home - English version (length 28.06 MB)], I found out the version I downloaded is called “setupengpro”. Last week I also downloaded the home edition which worked fine on my other computer but back then the file was called “setupeng” not “setupengpro”.
When I installed Avast using “setupengpro”, the resident protection won’t come on. So I uninstalled that version and re-installed using the old “setupeng” file from last week, and it worked fine with the resident protection coming on successfully. However, when I then tried to do both iAVS Update and Program Update, the error message of “Invalid file signature. Setup will terminate” comes up. I think maybe it’s tried to download the Pro version for update and that’s why it doesn’t work.
Could somebody at Avast look into this and fix it up please?
