If you have downloaded pirated antivirus software or any malicious software, it can disable Windows Defender to gain control over your computer. Many types of malware are designed to turn off or circumvent antivirus protections like Windows Defender, allowing them to operate undetected and make changes to your system without your knowledge. This can make your computer more vulnerable to further attacks and prevent legitimate security software from providing protection.
