Malware that has an embedded keylogger to capture all of the keystrokes and steal logins is considered:

Adware primarily focuses on displaying unsolicited advertisements and pop-ups, not covertly capturing keystrokes for data theft.

Spyware is a type of malware designed to secretly observe and record a user's activities without their knowledge or consent, often including the use of keyloggers to capture keystrokes and steal sensitive information like logins and passwords. This function directly aligns with the description of embedded keyloggers stealing logins.

Ransomware encrypts files or locks a system and demands payment to restore access, which is different from secretly stealing keystrokes.

Phishing is a social engineering technique that uses deceptive communication to trick users into revealing information, typically via email, and is not a type of malware that resides on a system as a keylogger.
