Why is Windows Defender not enough to protect your system?
Windows Defender Antivirus, while pre-installed on Windows 10 devices, offers only basic virus scanning capabilities and may not provide complete protection. Independent tests have shown that it often fails to block malware effectively. Additionally, Windows Defender may not receive frequent updates to keep up with emerging threats. Cybersecurity experts recommend using an additional antivirus solution for real-time scanning and prompt detection of malicious threats.

Why is antivirus software for Windows PCs important?
Antivirus software is crucial for Windows PCs due to the privacy risks involved in internet browsing. Companies often track user behavior to create personalized profiles for targeted advertising.
