Botnets, rootkits, and cryptojackers are some among them. Malware may generally cause some strange behavior in the server functioning, or sometimes it may stay hidden.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A complete scanning of Ubuntu may help detect malicious software, allowing you to address security issues quickly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There is an easy approach to keep your server free of malicious codes. Use ClamAV for this purpose.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h3 class=\"wp-block-heading\" style=\"font-size:16px\"><strong>What is ClamAV?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">ClamAV is a free, open-source antivirus software that helps to check for security threats like malware and viruses on your system. It may also be used as an email scanner and supports a variety of mail types.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">ClamAV antivirus software is also useful for detecting threats in compressed files (Zip, 7-Zip) and archives (tar, RAR). It is compatible with different platforms, including Linux distributions such as Ubuntu, Debian, CentOS, and many others.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" style=\"font-size:16px\"><strong>How to Install ClamAV for Malware Scanning on Ubuntu Server<\/strong><\/h2>\n\n\n\n<div class=\"schema-how-to wp-block-yoast-how-to-block\"><p class=\"schema-how-to-description\">ClanAV can be installed on Ubuntu server using the following commands:<\/p> <ul class=\"schema-how-to-steps\"><li class=\"schema-how-to-step\" id=\"how-to-step-1784020527301\"><strong class=\"schema-how-to-step-name\"><strong>Step1: <\/strong>Open a terminal using<br><\/strong> <p class=\"schema-how-to-step-text\"><strong>Press Ctrl + Alt + T<\/strong><\/p> <\/li><li class=\"schema-how-to-step\" id=\"how-to-step-1784020652379\"><strong class=\"schema-how-to-step-name\"><strong>Step2: <\/strong>Run the following command to install ClamAV<br><\/strong> <p class=\"schema-how-to-step-text\"><strong>sudo apt-get install clamav<\/strong><br><br><em>After entering the password and logging in, the installation procedure begins.\u00a0<\/em><br><\/p> <\/li><li class=\"schema-how-to-step\" id=\"how-to-step-1784020704307\"><strong class=\"schema-how-to-step-name\"><strong>Step3: <\/strong>Once it is completed, you need to update virus signatures.
