# ClamAV Troubleshooting

## Anti-virus Testing

To test the virus filter, it is necessary to download the eicar test virus email and send it using the command below (Replacing <emailonserver@example.com> with a real email account on the server). If the Anti-virus is working correctly you will see it get blocked and it will be listed in the maillog and in `Warden` -> `Logs` -> `Message Log`.

#### Disable Greylisting

If greylisting is enabled then you must disable it on the recipient domain before running these tests.

```
/usr/local/psa/bin/grey_listing --update-domain example.com -status off
```

#### AlmaLinux / CloudLinux / RHEL / Rocky Linux

```
wget http://www.eicar.org/download/eicar.com.txt
echo "TEST MESSAGE w/ ATTACHMENT" | mail -S smtp=localhost -r sender@test.com -s "A/V test example" -a eicar.com.txt emailonserver@example.com
```

#### Debian / Ubuntu

```
apt-get install s-nail
wget http://www.eicar.org/download/eicar.com.txt
echo "TEST MESSAGE w/ ATTACHMENT" | s-nail -S smtp=localhost -r sender@test.com -s "A/V test example" -a eicar.com.txt emailonserver@example.com
```

## ClamAV Tools

```

```

You can monitor the ClamAV daemon using the following command:

```

## Restarting ClamAV
