Antivirus is necessary even if you’re on a Mac or Windows device, which both come with some level of virus protection built in. For total protection with endpoint protection and response, and blocks against malware and potentially unwanted programs, it’s best to install a third-party antivirus software.
Antivirus software is designed to detect, block and then remove a virus. Antivirus programs use various techniques for detecting viruses. These include signature-based scanning, behavioral scanning and heuristics. Once detected, the antivirus software asks the user to perform appropriate action against the virus or selects a specific response from options like delete, repair or quarantine.
Spyware is a program that is engineered to steal valuable information from a computer. It works in stealth mode and is extremely difficult to detect and remove.
