Microsoft defender VS Norton 360




An antivirus guard is an application that helps to protect your computer from viruses and other malware. Antivirus guards are available as standalone programs or as part of a security suite. They can be downloaded from the internet, or they can be found as a pre-installed program on some computers. 

Do you really need a virus guard

Antivirus software is a critical line of defense against computer viruses and other malware. Unfortunately, many people don’t have a reliable antivirus software suite installed on their computers. This leaves them vulnerable to infection by viruses and other malware. The National Institute of Standards and Technology (NIST) has developed a series of tests to measure the effectiveness of antivirus software. The tests measure the software’s ability to detect and prevent the spread of viruses. The NIST tests show that antivirus software is effective at protecting computers from virus infection. However, antivirus software can’t always prevent the spread of viruses.
