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 desktops it primarily detects Windows viruses and malware.
Install with pacman by:
# pacman -Sy clamav
# change these to "yes" to start START_FRESHCLAM="yes" START_CLAMD="yes"
- To start clamav at boot edit Template:Filename and add clamav.
The daemon needs to be running for the virus update to be updated:
# /etc/rc.d/clamav start
Then update the virus definitions with:
The database files are saved in:
Scan for Viruses
Template:Codeline can be used to scan certain files, home directory, or an entire system:
$ clamscan myfile $ clamscan -r -i /home $ clamscan -r -i --exclude-dir=^/sys\|^/proc\|^/dev /
