With their code in the open, vulnerabilities are found and fixed more quickly than in the closed-source world of Windows and Mac OS.

Almost all Linux distributions, the Linux kernel, and the most prominent software are updated regularly.There’s no need for an antivirus vault here. This includes malicious software that, thanks to those restrictions, can’t infect other files or the OS itself. Thus, everything running under their account is subject to the same restrictions. Most people don’t log in to their Linux desktop with an account with root access.They use their distribution’s official software center and maybe some trusted repositories on top. Most people using Linux don’t use pirated programs and games that could come packaged with malicious software.

The reason we explain how viruses and antiviruses work is that it makes it simpler to understand why Linux is considered safe. If the file ends up malicious and there wasn’t a match on the online database, it gets registered there so other users can avoid it in the future before it infects their computers. At the same time, the antivirus creates signatures for it and compares them with an online database. If yes, it’s quarantined, moved to a sandboxed vault and restricted from direct access to the rest of the files in the system, unable to run and affect RAM’s contents. Is it trying to rapidly open, tweak and close dozens of files in succession? Is it trying to load differently named payloads in memory and keep them resident? Is it suspicious? “Heuristics” define methods that instead of checking a file for signs that show it’s a virus, monitor its behavior.

And they could pop up and infect systems more quickly than an antivirus maker could detect them, update their database and send it to each antivirus client.

Viruses upped the ante by learning how to hide, obfuscate and mutate their files to avoid detection.

They can redirect the user to malicious web pages, send anything they enter in forms to a third party, and exploit security holes in the browser or its add-ons to infect a PC with an extra payload.Īntivirus tools started as simple “file scanners” that scanned a PC’s storage to locate malicious files and remove them, then viruses got wiser and started renaming their files.Īntivirus tools caught on to that and started checking file fingerprints instead – basically hashes, comparing them to online databases of known malware. We can find web scripts on sites where malicious users managed to plant them among existing content.Worms can infect a machine without the user’s intervention by exploiting bugs in software and devices’ embedded firmware.Usually the downloaded files are from ambiguous sources. In most cases, the user himself downloads and runs those files, infecting his system without realizing it. Viruses and trojans propagate mostly through tainted executable files.To understand why Linux is deemed safe, we have to consider the most common types of malicious attacks that can target a computer. The takeaway: even if you don’t feel the effects of an infection, your PC can be a carrier.
