Detailed explanation-1: -Firewalls. A firewall is a software program or piece of hardware that blocks hackers from entering and using your computer. Hackers search the internet the way some telemarketers automatically dial random phone numbers.
Detailed explanation-2: -As software designed to interfere with a computer’s normal functioning, malware is a blanket term for viruses, trojans, and other destructive computer programs threat actors use to infect systems and networks in order to gain access to sensitive information.
Detailed explanation-3: -The primary difference between a virus and a worm is that viruses must be triggered by the activation of their host; whereas worms are stand-alone malicious programs that can self-replicate and propagate independently as soon as they have breached the system.
