AVG Free not updating properly

When I click both 'update' buttons, AVG Free updates, stops after 1 second and both Virus Definitions and Program sections display this line: "Last encountered error: Invalid file signature. Setup will terminate". And the last Virus Definition Update was 3 days ago. Does this mean AVG Free hasn't updated fully and isn't able to? When I've checked community queries and tried to 'repair' AVG Free, I only have 2 options 'Modify' or 'Uninstall'.  Can anyone help? Thanks!

Hello Jacqueline,

I appreciate your efforts and patience so far, Jacqueline.

It could be possible that the latest updated have failed to install completely or the connection with update server was interrupted. I would suggest you to uninstall (run AVG clear tool mentioned in the article) the current version and reinstall AVG to resolve the issue.

It seems you and I have the same problem. Check out this forum page: https://support.avg.com/answers?id=9060N000000UDXa

You'll find that there are others too who want to find out what's going on. There is a propsed solution on the first replies, but the solution didn't work for me, so I'm still waiting too.

Jacqueline, you can try the above steps which I have given you to reinstall the AVG program to fix the issue.

Hi Bhuvaneswari!
I have unstalled AVG Free using the remover and cleaner and successfully reinstalled - and the virus definitions are showing they were last updated 3 hours ago. Thank you very much for your help, I am very relieved and glad I queried the unusual error message. Thanks and have a great weekend!! Best wishes!
