Antivirus on Linux
Do you need antivirus on Linux, and what does ClamAV actually do?
Do I need antivirus?
Typically, Linux users don’t install antivirus for everyday use. Keep Linux and your apps updated, and download software from sources you trust.
Linux can still get malware. Be careful with unexpected downloads, browser extensions, and commands someone tells you to paste into a terminal.
When can it help?
Antivirus can be useful for checking downloaded files or files you share with other people. A file containing Windows malware can still be passed on from a Linux computer, even if it doesn’t run on Linux itself.
What is ClamAV?
ClamAV (opens in a new tab) is a free, open-source antivirus tool. You can use it to scan files and folders for known threats.
ClamAV is useful for checking files, but don’t expect the same automatic, all-round protection you might be used to from antivirus on Windows.
ClamAV’s threat database needs to stay updated so it can recognise newer threats.

A clean scan isn’t a guarantee
No scanner catches everything. A clean result doesn’t prove a download is safe. Keep using trusted sources and keep backups of files you care about.
