Best antivirus software for your Windows PC
Antivirus software is nearly as crucial as a PC’s operating system. Even if you’re well aware of potential threats and practice extreme caution, some threats just can’t be prevented without the extra help of an AV program – or a full antivirus suite.
You could, for example, visit a website that unintentionally displays malicious ads. Or accidentally click on a phishing email (it happens). Or get stung by a zero-day threat, where an undisclosed bug in Windows, your browser, or an installed program gives hackers entry to your system.
We’re not suggesting that PC security software is fool-proof. Antivirus software often can’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.
Our recommendations strike a balance between excellent protection, a worthwhile selection of features, and minimal impact on your PC’s performance.
What to look for in an antivirus suite
There are three basic requirements that an antivirus suite needs:
• High detection rate for malware and other threats
• Low impact on system resources
• An easy-to-use interface
That’s not all to consider, however. These days, many security suites come with extras such as a backup service for your most essential files, Android apps for mobile security, a more advanced firewall, family protection (read: child restriction) features, and the right to use the program on multiple PCs. Whether you need those extras depends on your personal situation.
How we test
First, we take a look at the interface to determine how easy or complicated it is. Does the interface make it easy to get at essential tools such as PC scans and password managers, for example, or is everything buried under multiple clicks? Are there elements that look like they should be clickable but aren’t? Are alerts interactive or purely informational, and does that make sense in context?
We also examine the features on offer. Every good antivirus suite should have the basics like scanning and real-time protection, but many vendors offer elements that go beyond basic security like password managers or firewalls. We try to discern whether any of these extra features are particularly useful, or just frills that look nice but don’t serve a practical purpose.
