The rate of cyber attacks has been increasing these days, and they are very dangerous and threatening. The cyberattack implies stealing, modifying, or destroying original data stored on the computer system or network. Many hackers or attackers steal or damage the data to pursue confidential information from the system. It may result in a significant loss for large or small organizations. So, to avoid such cyberattacks, you can use antivirus software.
What is Antivirus Software?
Antivirus Software is a software program that helps individuals to identify, avoid, or remove any attack or malware infection on computer devices or computer networks. Additionally, antivirus software removes computer viruses and prevents multiple threats or risks, like hijackers, Trojans, rootkits, adware, spyware, etc.
Whenever any virus enters your computer system, it may delete important files and folders, create spam in the computer device, access any confidential file, controls online activity, etc. There is an immense need to protect your computer system or networks from malware activities using antivirus software.
However, today, antivirus software is available for all major operating systems, like Microsoft Windows, Mac OS X, and Linux. But, most of the antivirus software devices are specially developed for Windows systems. This is because the Windows system is more prone to viruses and malware infections, and attackers attack mostly on Windows systems.
How does the Antivirus Software run?
When you install any antivirus software, it runs simultaneously with other computer programs. It scans all files and folders on the computer system or mobile device, and if there are any viruses or malware activities are detected, it prevents or removes them. Many antivirus software offers the feature of detecting all scams and malware activities in real-time. They identify any threat or virus as soon as it develops into the system and prevents it immediately.
Antivirus software also allows users to schedule scans for particular files or all files stored on the system. When users plan scans at a specific time, the antivirus virus software carries out scheduled scans automatically. Users can also perform an individual scan. The following are some crucial activities conducted by any antivirus program to prevent threats and malware:
