Title: Cannot Update Signatures in AVAST Free 17.4.2294
Post by: REDACTED on June 06, 2017, 05:13:22 PM
I recently noticed that my Avast Free antivirus 17.4.2294 was not updating its antivirus signatures. I tried changing various settings but to no avail. I then uninstalled using the Avast Clear tool and tried to reinstall but the installation failed, so downloaded and installed the offline installer. The installation appeared to go well, but I still can't update. I get the errors in the images below - downloading servers.def.vpx - then "unknown error"

I'm running alongside Malwarebytes 3 premium latest build and CryptoPrevent 8 - I was running these together until recently without apparent problems. Could anybody suggest what I could do to resolve the situation? Thanks in advance

Server may be offline

Does avast give any errors, saying it is not updated?

Do you recive stream updates?

High Pondus, thanks for your interest. I may be that I'm being stupid, I was getting a notification that definitions were out of date and then the error messages I posted above - but now, when I click on Update, I see the information posted in the attached image 5 -so does that mean I'm up to date? In the About Avast screen, I see the attached image info image 6. I thought that suggested a signature file dated in May, but perhaps I'm misreading it?

No you are not up-to-date.
Look at the date of the VPS and what date it is on the calender.

OK, I'm not as stupid as I thought - I wondered if I was misreading the date, but obviously not. After trying to update again, I eventually got the message in the image 7 below. Could you suggest what steps I might take to put this right?

Check the log files and see if there is anything in one (or more) of them that could be related to the problem.
Without it, we can only guess.

If I would have to that, I would say the Gremlins have gotten wet ;D

I never get my gremlins wet - I had just hoped for some advice on where to start looking. But hey, ho.......

Well, start with checking the log files.

I did start with checking the log files - can't spot anything. It seems I'd be better asking for advice elsewhere, I'm sorry to have troubled you.

Without information there is not much what we can do for you.

Change the DNS in your router to the one Google provides and check if it changes things.

My router and local DNS settings were already set to Google's. I supplied the error messages I received and details of the other security software installed. I omitted that I am running W7 Home Premium x64. Nothing jumps out at me in the logs.

I did find a satisfactory solution though - I ran the Avast uninstaller again and downloaded and installed Bitdefender,  which updates to the latest signatures without complaint.

That is not a solution but a workaround.
