Virus definitions not updating...?

Avast Free Antivirus / Premium Security
1

Hello there,

I have avast! free version on a Compaq laptop, using Windows Vista 2007 SP2.

It has been working fine for me with no problems until 11th September (4 days ago). Since that evening, I have been getting the avast! warning pop-up (red) telling me that the last attempt to update my virus definitions failed. Its says “click here to update now”. Clicking opens the avast! user interface on the Update tab (under “Maintenance”). When I click to update the virus definitions, the programme downloads file prod-ais.vpx, then I am told that my definitions are already up to date (today, it says I have version 110913-1).

But when I click “OK”, the programme tells me again that I am actually NOT up to date. This is the information displayed:

Current version: 110911-1 Release date: 11/09/2011 21:14:13 Number of definitions: 2,790,730

Your virus definitions are out of date! Latest virus definitions: 110913-1
Last update attempt: 1 minute ago.


Updating the programme has not helped (I am also apparently up to date there too, to version 6.0.1289, which may or may not be correct)

How do I get over this? I just want to be up to date, and I want avast to know that it is up to date!

For info, I am permanently connected to the internet and I have the settings on automatic update.

Thanks in advance for your help.

A bit more info: I’ve double checked and my registration has not expired. Also, when I click on the “About avast!” tab, it also states my current virus definitions version is 110911-1.

Try a repair of avast:
XP - Add Remove programs, select ‘avast! Anti-Virus,’ click the Change/Remove button and scroll down to Repair, click next and follow.

Vista, win7 - Control Panel, Programs & Features, uninstall a program, select ‘avast! Anti-Virus,’ click the Change/Remove button and scroll down to Repair, click next and follow.

You may need to reboot after the repair. This has in the past resolved this out of sync issue between reported and actual VPS version.

Thank you DavidR, that worked perfectly!

I had to restart the computer alright. Everything updating perfectly now.
