There is an eternal controversy between Linux users: do we need an antivirus in Linux? In Windows, it’s clear that without an antivirus, that PC will get viruses. When the computer shuts itself down, strange windows with text that you do not understand, or tens of windows that you can not close, if emails are sent automatically, the reason can only be one: the system has a virus. The main reason is that Windows is running. But Linux has very few viruses. For a virus, a Linux system is complicated to infect; and if a system has been infected, the destruction made by that virus is minor due to the very well-tuned permission system. Linux uses an extremely efficient permission system. In Windows, the user (and every installed program) has the right to do almost everything he wants in the system. In Linux, most programs (99.99%) are installed from the software repositories. Well, in these repositories they check and scan packages, so it’s impossible to virus your system if you only install programs from official repositories.
Antivirus is required if you have Windows in dual-boot with Linux and also to protect the Windows systems you are in contact with (you have downloaded an executable file from somewhere, scanned it in Linux and forward it to another user). In other words, use the antivirus in Linux to scan files from Windows, because Windows is easily more infected, being infected if it comes through Linux. Yes, you can run web servers or mail servers to scan files from Windows – to prevent infected Windows machines from uploading viruses on the Linux server and from here to get to other Windows machines to affect them.
