Antivirus software is nearly as crucial as a PCâ€™s operating system. Even if youâ€™re well aware of potential threats and practice extreme caution, some threats just canâ€™t be prevented without the extra help of an AV programâ€”or a full antivirus suite.Â
You could, for example, visit a website that unintentionally displays malicious ads. Or accidentally click on a phishing email (it happens!). Or get stung byÂ a zero-day threat, where an undisclosed bug in Windows, your browser, or an installed program gives hackers entry to your system.
Weâ€™re not suggesting that PC security software is fool-proof. Antivirus software often canâ€™t do much to stop zero-day exploits, for example. But it can detect when the undisclosed vulnerability is used to install other nasty bits, like ransomware, on your machine. Anyone who actively uses email, clicks on links, and downloads programs will benefit from an antivirus suite.
