# ClamAV
|
|||
|
|
[Arch Wiki](https://wiki.archlinux.org/title/ClamAV)
|

|
|
Clam AntiVirus is an open source (GPL) anti-virus toolkit for UNIX. It provides a number of utilities including a flexible and scalable multi-threaded daemon, a command line scanner and advanced tool for automatic database updates. Because ClamAV's main use is on file/mail servers for [Windows](../windows/Windows.md) desktops, it primarily detects [Windows](../windows/Windows.md) viruses and malware with its built-in signatures.
|

|
|
|
|||
|
|
## Usage
|
|||
|
|
### Updating database
|
|||
|
|
Update the virus definitions with:
|
|||
|
|
```shell
|
|||
|
|
freshclam
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
The database files are saved in:
|
|||
|
|
```
|
|||
|
|
/var/lib/clamav/daily.cvd
|
|||
|
|
/var/lib/clamav/main.cvd
|
|||
|
|
/var/lib/clamav/bytecode.cvd
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Start/Enable`clamav-freshclam.service` so that the virus definitions are kept recent.
|
|||
|
|
|
|||
|
|
### Starting the daemon
|
|||
|
|
|
|||
|
|
**Note:**
|
|||
|
|
- You will need to run `freshclam` before starting the service for the first time or you will run into trouble/errors which will prevent ClamAV from starting correctly.
|
|||
|
|
- The daemon is not needed if you only want to perform stand-alone scans. See [Scan for viruses](https://wiki.archlinux.org/title/ClamAV#Scan_for_viruses) below.
|
|||
|
|
|
|||
|
|
The service is called `clamav-daemon.service`.
