Syncing with Gmail has stopped suddenly

Hello,
I have installed eM Client (in FR) a few days ago. It started working fine with my Gmail account - everything was nicely synchronised without me needing to configure a lot of things - so I was quite happy.
My emails have stopped suddenly synchronising since last Sunday.
I get the message below in “Operations”.
Many thanks in advance for any help/advice!

As a test, can you completely disable any anti-virus. firewall, proxy or VPN, then try again.

Thank you Gary! I disconnected temporarily my antivirus (AVAST free version) and it now works!

What should I do to avoid this issue in future? Use another antivirus?

As a temporary solution, disable the Avast Mail Shield, then you can re-enable Avast to protect the rest of your system. Any attachments you open in eM Client will still be screened by Avast, so it is not like you are completely exposed.

Thank you Gary!

I would prefer a permanent solution though. Is AVAST the only antivirus that creates this problem? In other words, can I get rid of this issue if I use another antivirus?

Hi @sprieal

Personally I have a thing about Avast/AVG that I have commented on before.

If you are using Windows 10 you would be as well using Microsoft Defender to protect your system and remove Avast.
In addition you could also use Malwarebytes that monitors your system in the background.
