Why does running anti-malware software from another operating system (such as a Rescue CDUSB stick) do a better job than running the anti-malware software from Windows?

Running anti-malware software from another operating system, like a Rescue CD or USB stick, often provides a better detection and removal capability because it operates outside the infected Windows environment. Malware can hide its processes and files while Windows is running, making it difficult for software to detect and remove them effectively. Additionally, a clean OS environment allows the software to scan the hard drive without interference from malicious programs that may be running in the background. This approach can lead to a more thorough cleaning of the system.
