Your operating system is protected by an antivirus program, which closes several potential security holes. Utilizing antivirus technology offers many benefits, and these benefits far outweigh any potential disadvantages such as the time it takes to scan your computer.
Protection In Real-Time
You cannot scan files as they enter your computer without an antivirus program, nor can you scan programs as they run. A real-time scanner provides a shield for your system in most antivirus programs. Your antivirus program can delete an infected file or program on the spot or move it to a special quarantine folder if it detects one. Whenever your antivirus quarantines a file, it prevents it from interacting with the rest of the computer.
Best Antivirus 2022 programs allow you to perform a “boot-time scan” when the program starts. When you delete a virus that is sophisticated enough, and if the operating system is active, it can duplicate itself. Once you initiate a boot-time scan, your antivirus program will shut down Windows and restart the computer. The program will then scan the entire hard drive for viruses and other forms of malware. If any viruses are detected in the scanning process, they will be deleted since you have deactivated the operating system.
Individual Files Are Scanned
You might need to run a program or open a file, but aren’t sure if it’s safe to do so. You can either gamble on the safety of the file or application, or limit your access to it if you don’t have an antivirus program. Before you interact with a file or program, you can scan it with one. By scanning suspicious files before you open them, you can prevent Trojans and other viruses from invading large areas. You should always use this feature when you download files from the Internet or receive them from others you do not completely trust.
Sensitive Information Protection
It is possible for viruses to use your machine as a relay for other forms of malware if your machine does not have an antivirus application protecting it. It may even be possible for you to inadvertently send viruses to anyone on your contact list if your computer is infected. It is also possible that all of your most sensitive information has been uploaded to networks of infected computers. Botnets are networks that specialize in stealing credit card numbers and other valuable information and sending them to criminals who then sell them to third parties. A virus such as the “Conficker” worm is an example.
