A boot scan, also known as pre-boot scan or shoe scan, virus scanner is an advanced tool that is utilized by antimalware software to identify and remove malware that could not be detected by conventional scanning tools. This type of scan could be scheduled to be scheduled to run automatically at regular intervals, or manually by the user if they suspect that their computer has been infected. Many antivirus programs allow users to select the degree of sensitivity for the boot scan and also determine what actions are to be taken if an attack is detected.
A boot scan is efficient because it allows an antimalware program detect files that are being used by the OS. These files are not easily deleted because they are always accessed by the OS. They will show an Access Denied message when you attempt to delete them. The boot scan will identify these files and permit antivirus software to erase them before the OS can begin using them.
The duration of a boot-scan will vary based on a variety factors, such as the speed and number of system files that are being examined. It also depends on whether the machine is in use during the scanning process. This kind of scan could take longer than a typical anti-virus scan due to the thoroughness of the process.
