ClamAV: Fixing freshclam's Hanging Up

This post is about a small tip of ClamAV, actually ClamAV Unofficial Sigs in my case, troubleshooting.

I found freshclam freezed up in my OpenBSD server the other day:

# freshclam
ClamAV update process started at Fri Mar 22 22:32:33 2019
WARNING: Your ClamAV installation is OUTDATED!
WARNING: Local version: 0.100.2 Recommended version: 0.101.1
DON'T PANIC! Read https://www.clamav.net/documents/upgrading-clamav
main.cvd is up to date (version: 58, sigs: 4566249, f-level: 60, builder: sigmgr)

Downloading daily-25379.cdiff [100%]
Downloading daily-25380.cdiff [100%]

Waiting or retrying didn't make any meaning.

The reason often seems in the database file.
Try to renew it by moving the original file to /tmp:

# # OpenBSD:
# mv /var/db/clamav/daily.cld /tmp
# # Manjaro Linux:
# mv /var/lib/clamav/daily.cld /tmp

Note: The directory is up to your operating system.

Run freshclam and check if it works well:

# freshclam

If it's all right, delete the old file:

# rm /tmp/daily.cld

I'm happy if this solution would help someone someday : )
Happy securing.
