What’s in antivirus software? All the pieces you may need (or not)
In the days of tech yore, antivirus software was just that. You installed the application and let it scan your system for malware.
But as protecting your PC became more complicated, vendors slowly morphed their offerings into full suites. Nowadays, a firewall and other safeguards like a browser extension, password manager, and VPN get dropped onto your system. You might even get a handful of utilities focused on optimizing your computer, rather than defending it.
To help you figure out what components are most important — as well as necessary for your situation — we’ve broken down the most common elements of today’s antivirus software.
Antivirus
At the heart of every antivirus plan is the engine that detects threats to your PC. These days, modern antivirus software both anticipates and roots out the presence of viruses and other malware, including ransomware.
Blocking malware before it even hits your computer is a key defense against situations like your PC being commandeered for botnet attacks, having your data stolen, and getting locked out of your documents and folders. It also can stop creepy behavior like being spied on through your webcam or having everything you do recorded (including what you type).
An antivirus engine does this by screening the websites you visit, as well as the email and apps on your PC, for phishing links and potential malicious downloads. Phishing attempts usually try to steal your passwords, credit card details, or other personal information by pretending to be a legitimate site and then capturing whatever data you input.
