![]() The –remove switch tells ClamAV to remove infected files. This is useful if you only want to know which files are infected, and you don’t want to remove them. The –infected switch tells ClamAV to only report infected files. Step 4 : Use –infected, –remove, and –recursive switchesĬlamAV has a number of switches that can be used to customize its behavior. Using a tool like ClamAV to scan your website’s directories for malware is an important part of maintaining a secure and SEO-friendly website.Īs an example With the command : $ clamscan -r /home*/*/public_htmlĬlamAV can scan all public_html folders within any home directories that are two levels deep, which can help detect and remove any malicious files or scripts that could harm your website’s visitors or negatively impact your search engine rankings. To update the ClamAV virus database, run the following command: $ sudo freshclam Step 3 : Scanning Folders with ClamAV This database is updated regularly, so it is important to update it before scanning for viruses. Step 2 : Update the ClamAV virus databaseĬlamAV uses a virus database to identify known malware. This will install the ClamAV package and all of its dependencies. To install ClamAV, open a terminal window and run the following command: $ sudo apt install clamav A running instance of Debian or Ubuntu Server 22.04, 20.04, or 18.04.In this tutorial, we will show you how to install and use ClamAV on Ubuntu Server 22.04, 20.04, and 18.04. ClamAV is available for a variety of platforms, including Ubuntu. It can be used to scan files and directories for viruses, worms, Trojan horses, and other malware.

You have now scheduled a ClamAV scan to happen on your home directory at 3:30 AM tomorrow. You can use the at command to schedule clamscan or freshclam. It is always best to manually check the files you delete, if you are not totally sure that this is what you want to do. You can add -remove to the clamscan or clamdscan command-line. Look for it in the processt list, or use this handy shortcut: ps ax | grep lamd The daemon will then accept connections to it via the IP address and Port combination you specify. To do this, you simply have to modify the nf file and add TCPSocket PORTNUMBER and TCPAddr IPADDRESS arguments to the nf file and reload the daemon. There are cases where you may want ClamAV daemon to act as a scanner for other systems, so you don't have to run everything locally on the system. The clamav-daemon package creates a 'clamav' user in order to allow ClamAV to scan system files, such as your mail spool, you can add clamav to the group that owns the files. This speeds up virus scanning as the program is always in memory. ![]() Lots of programs, especially e-mail servers, can connect to a ClamAV daemon. You can then use clamdscan where you would previously have used clamscan. For example, if using Wine and it deletes an infected file, it could break a program without having the data saved. When scanning recursively, one may generate a report via: sudo clamscan -v -r /FOLDERTOSCAN | grep FOUND > /path/to/save/report/file.txtĬlamAV doesn't disinfect files, it either moves or removes them. If you want to check all files on the system, use the sudo command (see UsingSudo for more information). When ClamAV has finished scanning it will report a summary: - SCAN SUMMARY -ĬlamAV can only read files that the user running it can read. Use clamscan to check nearly all files on the computer, and report only warnings and infections: sudo clamscan -max-filesize=3999M -max-scansize=3999M -exclude-dir=/sys/* -i -r / If you are using a http proxy to connect to the internet you will have to edit the file /etc/clamav/nf adding: HTTPProxyServer serveraddress Main.cvd is up to date (version: 31, sigs: 33079, f-level: 4, builder: tkojm)ĭaily.cvd is up to date (version: 855, sigs: 714, f-level: 4, builder: ccordes) You will see an output like this: sudo freshclamĬlamAV update process started at Wed Apr 27 00:06:47 2005 If one wants a GUI, then install the package clamtk.
