How to be sure ClamAV database is up to date?

Question

I am currently having an issue with ClamAV and freshclam on Centos 6.9.

I have the last Clam engine 0.99.2, and a working internet connection. Even if I run the # freshclam -v command ( it only returns a security warning about unsecure permission of freshclam.conf) before a # clamscan, clamAV return me this warning :

LibClamAV Warning: ************************************************** LibClamAV Warning: *** The virus database is older than 7 days. *** LibClamAV Warning: *** Please update it IMMEDIATELY! *** LibClamAV Warning: **************************************************

So my questions are : how can I know when the last update was done ? Or make sure the virus database is up-to-date ?

PS : I've tested the clamscan with eicar test file and it detects it.

Answer 1

You have 2 questions:

1. How can I know when the last update was done ?

host -t txt current.cvd.clamav.net; perl -e 'printf "%d\n", time;'

This will tell you when clamav made available the last update.

2. Make sure the virus database is up-to-date ?

First you need to understand why you get the security warning. If you post the warning here maybe we'd have a better chance to help you.

Then I recommend you look in the log at /var/log/clamav/freshclam.log

Also, if you have selinux enabled, you'd have to run this: setsebool -P antivirus_can_scan_system 1. If by any chance the error is something like this During database load : LibClamAV Warning: RWX mapping denied: Can't allocate RWX Memory: Permission denied then clearly your solution is the command I mentioned above.
