Question Typical size of clamav files

[mirazbira]

Hello guys, I would like ask you what is typical size of clamav files "main.cld" and "daily.cld" on your server ? Is it normal that size of each file is almost 400 MB ? Can this size be reduced ? I use clamav on small webserver with about 10 websites. Lets say simple I am looking to clean up some space on server. And it seems clamav take up a quite a lot of space from my point of view .

hello Mirazbira,
I've found too old thread. But probably nothing was changed since this time.
in two words, looks like updates for signatures are not rotated/compacted automatically.

on my Ubuntu 20.04 after fresh clamav installation it is about 100Mb each:

Expand/Collapse Block: spoiler

:~# ls -lah /var/lib/clamav/
total 214M
drwxr-xr-x 2 clamav clamav 4.0K Apr 20 04:10 .
drwxr-xr-x 52 root root 4.0K Apr 20 04:09 ..
-rw-r--r-- 1 clamav clamav 287K Apr 20 04:10 bytecode.cvd
-rw-r--r-- 1 clamav clamav 101M Apr 20 04:09 daily.cvd
-rw-r--r-- 1 clamav clamav 113M Apr 20 04:10 main.cvd

so, probably if you are not using self-written signatures , you can try to remove these files and download fresh updates from clamav servers.
It should help to reduce size about twice.

p.s> probably it would be a good idea not to remove them first time, before you will be sure that it works.
