* Although viruses and spyware are less common in Linux systems, they do exist. Furthermore, many users share files with Windows users, either on their own computer or on LANs. ClamAV is useful for checking these files.
* Install ClamAV AntiVirus Server:
sudo apt-get install clamav
If you get errors, try running the command again
