Answer:-
An unwanted program running on a computer is called malware. Malware, short for "malicious software," includes viruses, spyware, trojans, and adware that can harm your computer, steal personal information, or slow down your system. Often, these programs install without your knowledge, sometimes bundled with legitimate software downloads or through infected websites. Malware can cause data loss, compromise privacy, and make computers vulnerable to hackers. Good antivirus software and careful browsing habits help detect and remove these unwanted programs, keeping your system secure and running smoothly.
