Does The M.D.A. Or The W.D. Contain Spyware/s?

Question

Most experts through their own websites have listed a number of free antiviruses containing hidden spyware without giving any warning/s for a computer user/s, and that one should totally avoid using any one of the listed free antivirus completely,while Microsoft claims the rival free antiviruses are mostly guilty themselves,as mentioned in their website.I have explored every free antivirus one by one and found no evidences of spyware or hackware or anything nasty hidden in the installed free antivirus.What i did notice oddly enough that in 2026,the installed M.D.A. and or W.D. doesn't mind in allowing a/all dangerous download/s in getting downloaded, installed, and explored.In every case of mine the solely installed M.D.A. and or W.D. has lost against an installed computer virus and the installed antivirus was instantly wrecked or was being over taken by the installed computer virus.The only way out was to go ahead with a full reset of Windows 11.I always many time over given the M.D.A. and the W.D. many chances for it to show it can do it's job well in protecting my computer on a professional level,but it still has not even come close in getting a golden award,but sadly it only earned a silver award or mostly a third place for trying to do it's job.

Microsoft Defender Antivirus (M.D.A.) and Windows Defender (W.D.) are designed to protect your computer from various threats, including spyware and viruses. However, no antivirus solution is perfect, and there can be instances where malware may bypass detection. It's important to ensure that your software is up to date and that you are using the latest definitions to maximize protection against potential threats.

While some free antivirus programs may have been reported to contain spyware, Microsoft Defender is generally considered a reliable option. It is crucial to download software from reputable sources and to be cautious with downloads, as malicious software can sometimes be installed without your knowledge.

If you are experiencing issues with infections that lead to the need for a full reset, it may be beneficial to review your security practices, such as avoiding suspicious downloads and ensuring that your operating system and antivirus software are regularly updated. Additionally, using a combination of security measures, such as a firewall and safe browsing habits, can enhance your overall protection.
