What effect does installing an anti-malware app often have on existing malware areas in Windows security?

When an anti-malware application is installed on a Windows system, it often integrates with the Windows security framework and can take over as the default security provider. This transition means that the newly installed application may manage real-time protection, scanning schedules, and threat response. The system's behavior may change as it prioritizes the new software for threat detection and response instead of relying on the built-in Windows Security features.

In this context, the assumption that Windows security will designate the new anti-malware app as the default stems from how operating systems are designed to work with third-party security solutions. Typically, Windows will allow one primary security application to handle malware scanning and protection tasks to avoid conflicts and performance issues caused by running multiple security programs simultaneously.

While the new application may not automatically delete or quarantine existing malware upon installation, it will usually take precedence in handling security threats moving forward. Therefore, the installation of an anti-malware app does not necessarily mean that existing malware is deleted or quarantined immediately; rather, it changes the operational dynamics of how security is managed on the system.
