G-Lock Spam Combat Blocked

[antonalfredo]

Hello.

I've been using G-Lock Spam Combat

https://www.glocksoft.com/spamcombat/

with Avast Free

https://www.avast.com/en-us/free-antivirus-download-t2

on Windows 10 Home 64x

and worked fine until two weeks ago, when it could no longer download e-mail headers. The error is "10091: Network subsystem is unusable". The problem persists even after I add the G-Lock folder in

Avast Free Settings -> General -> Exceptions

and in

Blocked and Allowed Apps -> Allowed Apps

although only the Ransomware Shield shows up for features that will allow the app to run.

Meanwhile, MS Outlook 365 can still download e-mail correctly.

However, when I go to

Avast Free settings -> Protection -> Core Shields -> Mail Shield

and disable "Scan Inbound emails (POP3/IMAP4)", G-Lock is able to download e-mail headers correctly.

How can I make G-Lock work without disable "Scan Inbound emails".

Thanks for the help.
