Final answer:
Spyware is the type of malware that collects users' personal information without their knowledge. It is different from viruses, Trojan horses, and worms in its purpose and behavior. Avoiding suspicious links and using security software are good practices to protect against spyware.
Step-by-step explanation:
The type of malware that collects a user's personal information or details about their browsing habits without their knowledge is known as spyware. Hackers use spyware as one of the methods to discreetly monitor and collect data from users. This can include keylogging to capture keystrokes, screen captures, or stealing sensitive information such as credit card numbers and passwords.
Spyware differs from other forms of malware such as viruses, which typically damage or disrupt systems; Trojan horses, which disguise themselves as harmless programs to trick users into installing them; and worms, which self-replicate to spread to other computers. The aim of spyware is to sneak into your device and remain undetected, often profiting from stolen data or by selling your browsing information to advertisers or other third parties.
It's important to be vigilant against spyware by avoiding clicking on suspicious links, not downloading software from untrusted sources, and using comprehensive security software. These are useful practices to deter hackers who employ various methods to lure people into giving out personal information.
