So, I just installed Mailborder v5 on the client. Mailborder using ClamAV for detecting viruses and the accuracy is very good. ClamAV on Mailborder has been customized and ready to use. So, when you install Mailborder, ClamAV will be included.

Unfortunately, when configuring ClamAV, the internet is not very good. So that, i found an error when the system configuring ClamAV:

Tue Jun 23 14:13:46 2020 -> ClamAV update process started at Tue Jun 23 14:13:46 2020
Tue Jun 23 14:13:46 2020 -> daily database available for download (remote version: 25851)
Tue Jun 23 14:14:16 2020 -> ^Download failed (28) Tue Jun 23 14:14:16 2020 -> ^ Message: Timeout was reached
Tue Jun 23 14:14:16 2020 -> ^getcvd: Can't download daily.cvd from
Tue Jun 23 14:14:16 2020 -> Trying again in 5 secs...


This problem can be happened cause ClamAV database failed to download and it’s also happened depend on your internet connection.

So that, i stop the ClamAV services using systemctl stop clamav-freshclam. And run freshclam manually. But also found the same error.

To solve this, we have many different ways.

  1. Download the database manually, using wget or curl and place it on /var/lib/clamav/.
  2. Increase ClamAV timeout

Download the database manually is not good because ClamAV has many databases for viruses. you have to download it manually, it’s not good, trust me.

Best solution is number 2, increase ClamAV Timeout. Edit /etc/clamav/freshclam.conf and change this:

ReceiveTimeout 30

To this:

ReceiveTimeout 300

Make sure you stop ClamAV

systemctl stop clamav-freshclam

Then run freshclam manually

Preview(opens in a new tab)


Wait it, until download finished and start ClamAV.

systemctl start clamav-freshclam

Now, your ClamAV will not error again. Hope this help, Thank you!

Easy fix thanks! bout finding a way to report this to the Clamav team? I checked them out and found a fancy big corp. website, a github link, but no issue page. Many people will have issues with downloading 108mb in 30seconds.or less.

The advice about using using wget or curl to manually download the Clamav data is obsolete and will no longer work.

April 29, 2021
programs like wget have been blocked entirely (error code 403) and the whole database files like daily.cvd, main.cvd, and bytecode.cvd are being rate limited (error code 429).

So you must change the timeout value in the config file and also ensure that you are not trying to do downloads more than once an hour or so or you will be blocked for several hours.

    Hi Jasper,

    Thank you!, yes clamav have been blocked using wget. but you can also download it through your browser.
