Hello Piking,
Welcome to the world of Windows 11! It's great that you've made the leap to a new PC, but I understand that adjusting to a new operating system can be a bit daunting.
Regarding your question about Windows Security (formerly known as Windows Defender), you're correct that it comes pre-installed with Windows 11 and provides robust protection against malware, viruses, and other security threats. Here are a few key points to consider:
1. Real-Time Protection: Windows Security offers real-time protection that actively scans for threats while you use your PC. This is comparable to what you’d find in McAfee and other third-party antivirus solutions.
2. Built-In Features: It includes several additional features like ransomware protection, cloud-delivered protection, and a built-in firewall that help safeguard your system from various threats.
3. Performance: Since Windows Security is integrated into the operating system, you might find it to be more efficient and less resource-intensive compared to some third-party options like McAfee, which can occasionally slow down system performance.
4. Regular Updates: Windows Security receives regular updates from Microsoft, ensuring that it stays current with the latest threats and vulnerabilities.
5. Compatibility: If you choose to use Windows Security, you should generally uninstall McAfee to avoid potential conflicts between the two programs, as having multiple antivirus software can lead to performance issues and false positives.
While Windows Security is quite robust, some users still prefer additional security measures, especially if they engage in risky activities online (like downloading files from untrusted sources). If you feel you need that extra layer of protection, many users find that a lightweight antivirus solution works well alongside Windows Security.
Ultimately, it's about finding what makes you feel comfortable. If saving some money while still ensuring your PC's safety sounds appealing, Windows Security is a solid choice!
Feel free to ask if you need help with anything else regarding your new Dell PC or Windows 11!
Happy computing!
