ClamAV stopped working

Problem reported by Patrick Mattson - 12/22/2021 at 5:26 PM

Submitted

I seem to have a problem with Clam AV since moving to 8025. I had an open ticket prior to the new version, they thought the new version might fix things.

Delivery logs are showing the following error: ClamD Checks error: No connection could be made because the target machine actively refused it 127.0.0.1:3310 | error

I checked my logs on December 18, was running Oct 2021 version, and this string was not there.

I tried to remove the two config files and restart the service, it created new config files, but still seeing the issue.

Is anyone else seeing this?

Hello Patrick,

Thank you for posting to the community.

I just did an upgrade from 7957 to 8025. After this, I tested clam av by sending an email and this is what I got.

It appears that ClamAV is working as expected when you upgrade. I understand that you currently have a ticket open about ClamAV not working we will continue working with you to resolve the issue. If anyone else is having this issue please let us know and open a ticket with us so we can help you.

Thanks Zach. Which log are you seeing those in?

I am not seeing Windows Defender referenced in the Delivery Logs.

Hey Patrick,

This is in the spam checks log. You can locate this if you go to TroubleShooting->Logs You need to make sure that your spam checks are set to detailed.

When you get an email you will see it populate with this information. Also to see the Defender logs you need to make sure that it's enabled by going to Settings->AntiVirus. Please let me know if you have any questions.

Happy Holidays,

I just had ClamAV stop working on my server at work, but still working fine on the one at home. I looked at the conf files, and they had 8.3 paths (C:\PROGRA~2\SMARTE~1\...). That's bad form. I changed them all to quoted long file name paths ("C:\Program Files (x86)\SmarterTools\SmarterMail\Service\Clam\...") and now both servers are working fine again.

Hey Pjeski,

Thanks for letting us know your solution. May I ask which config file that was specifically?

Kind Regards,

Fixing "C:\Program Files (x86)\SmarterTools\SmarterMail\Service\Clam\etc\clamd.conf" is what got clam working again. I also fixed "C:\Program Files (x86)\SmarterTools\SmarterMail\Service\Clam\etc\freshclam.conf" for good measure.

We had this "ClamD Checks error: No connection..." after upgrading to the (June-15) build. Seems like it was also causing excessive CPU utilization.

We applied the fix listed above and seems to be working again. Thank you @Patrick Jeski for finding this and sharing!!!
