How to use clam antivirus antivirus in Linux

For computer systems, viruses are the biggest danger. Clam Antivirus is a good virus killing software. It can run on Linux, Windows and other systems. In Linux, you need to use Clam Antivirus on the command line. The following small series will introduce you to the Linux installation using Clam Antivirus.

It's good and convenient to use the Clam engine directly from the command line, such as when you connect to another machine via SSH, or when working on a computer with a very poor desktop system. It's also good for servers because they most want to do anti-virus scanning to prevent viruses from spreading to clients connecting to this server.

Installation

You should install the Clam Antivirus engine before you start. You can search for “clam antivirus” on the corresponding package management tool and install the main package. All dependencies should be processed automatically.

If you are using Ubuntu, you can also install it by running sudo apt-get install clamav clamav-freshclam, or Fedora: sudo yum install clamav clamav-updates . Since Clam is very lightweight, downloading and installing packages shouldn't take too much time.

update the virus database

The first thing after installation should be upgraded virus database to detect the latest threats. This step can be done easily by running sudo freshclam. It will immediately connect to the Clam server and download the latest virus information. The first download may take a while because there is no information on the local. Subsequent updates are much faster, because freshclam only downloads updates that are not available locally.

example

Once the virus database after the upgrade is complete you can start using clamscan scanned. Running clamscan –help on the terminal lists a number of different options so you can customize the scan options. However, if you want to be simple, you can run clamscan -r /home/usr directly to scan the usr folder in your home. The parameter -r is important, otherwise Clam will simply scan the files in usr and ignore the various subfolders inside.

Of course, if you need to scan another directory, just adjust the path. If you have other special needs, look at the output of clamscan –help. Everyone's needs are different, and some are not satisfied with the simple -r deep scan.
