This monoculture, a clueless Windows user base and the malware industry concentrating on Microsoft make Do I Really Need to Buy an Antivirus Program? depend on whether your computer runs a Unix/Linux or a Windows operating system. Linux/Unix systems are not necessarily more secure than Windows but free or Open Source antivirus programs can be state-of-the art protection in the Linux/Unix realm, whereas in the Windows domain this is definitively not the case as a result of the three factors outlined above.

Threat sophistication, e. g. Trojan horses, keyloggers, password stealers, identity theft and ransomware just to name a few, and the semantic game plaid by vendors of paid antivirus programs demand that you had better look for optimal (likely 360°) protection against malware.
