Detailed explanation-1: -Some computer viruses are programmed to harm your computer by damaging programs, deleting files, or reformatting the hard drive. Others simply replicate themselves or flood a network with traffic, making it impossible to perform any internet activity.
Detailed explanation-2: -Typically, computer viruses spread through malicious online downloads, infected email attachments, or by plugging in infected hardware like an external flash drive (USB stick). Computer viruses can spread through almost any method of file sharing, as long as the virus can avoid detection by antivirus programs.
Detailed explanation-3: -A worm, conversely, doesn’t need a host system and is capable of spreading across a network and any systems connected to the network without user action. Once on a system, worms are known to drop malware (often ransomware) or open a backdoor.
Detailed explanation-4: -A computer virus is an illegal, harmful, or malicious program that can change the way your computer runs and behaves. Some of these programs seek to cause as much damage as possible to the endpoint devices they infect, like altering software programs or corrupting data.
