For two decades, antivirus software has been a familiar presence for anyone who has used a PC. With a constant barrage of advertisements warning users about potential risks, the importance of maintaining robust computer security has never been more pronounced. While Windows 11 offers its own built-in security features, many users find that supplementing this with third-party antivirus solutions can enhance their sense of safety. These alternatives often provide quicker updates, a wider array of options, and additional benefits such as VPNs, browser plugins, and dedicated tech support for troubleshooting.
A significant aspect of computer security hinges on user behavior. To mitigate risks, it is advisable to avoid clicking on links from unfamiliar email senders and to refrain from running downloaded applications from unknown sources. Additionally, the practice of reusing passwords can expose users to unnecessary vulnerabilities.
How we tested
Our comprehensive evaluation of antivirus applications involved a meticulous testing process. Each software was installed on a Windows 11 PC, fully updated with the latest security patches. To ensure a safe testing environment, we utilized specially crafted files from Eicar.org to simulate virus attacks, steering clear of real threats or the dark web. Furthermore, we assessed the applications’ responses to potential malware by visiting the Wicar.org antivirus test site.
Each product was tasked with scanning the SSD of the Windows 11 PC, which contained a mix of applications, documents, and the operating system itself. We carefully recorded the duration of each scan and consulted reports from independent security testing laboratories, such as SE Labs and AV-Test, to identify which antivirus packages garnered praise from industry experts.
