On how does antivirus works? List and explain the generation of antivirus approaches
Answers
Virus – a piece of code that is capable of copying itself and typically has a detrimental effect, such as corrupting a system or destroying data on an individual computer. A computer virus operates by inserting or attaching itself to a legitimate program or document that supports macros in order to execute its code.
Worm – a malware computer program that replicates itself so it can spread to other computers, often, via a network. Almost always causing harm to the network, worms rely on security failures on the target computer in order to initially gain access.
Malware – also known as malicious software, is a broad term used to refer to viruses, worms, ransomware, Trojan horses, keyloggers, rootkits, spyware, adware and other malicious software. Malware is designed to disrupt normal computer or mobile operations, gather sensitive information, get access to private computer systems and even to show unwanted advertising.
Antivirus software, sometimes known as anti-malware software, is designed to detect, prevent and take action to disarm or remove malicious software from your computer such as viruses, worms and Trojan horses. It may also prevent or remove unwanted spyware and adware in addition to other types of malicious programs........
