Install an Anti-Virus

Installing an anti-virus might not be a bad idea, specially if you share files. ClamAV is a free anti-virus you can easily install on your server.

Install by running:

apt-get install clamav clamav-daemon -y

Perform first scan

clamscan --verbose --recursive

Update it

We need to first stop the service to update clamav

systemctl stop clamav-freshclam
freshclam

Then start it

systemctl start clamav-freshclam
systemctl enable clamav-freshclam
