Trojans: Trojans disguise themselves as legitimate software but secretly install malicious programs on the system.

Ransomware: Ransomware locks or encrypts files and demands payment for restoring access.

Spyware: Spyware secretly monitors user activities and collects personal information such as passwords or browsing history.

Adware: Adware displays unwanted advertisements and may track browsing behavior.
