Many antivirus applications offer the option of a boot scan. This is a powerful tool to eliminate malware that can’t be removed by normal methods. This kind of virus is able to be hidden in the boot sector or even encrypt files. It is typically more difficult to remove than a normal runtime scan. It is essential that you make sure to utilize an antivirus that has the ability to perform a boot scan as this kind of virus isn’t only more difficult to detect but it can also be extremely harmful.
Avast Boot Scan is a powerful way to identify hidden threats. It can detect threats that are typically missed by scans that run at runtime and is able to eliminate it without affecting the functioning of Windows. However, it can take some time to complete the scan as it has to look through every single file on your system. It is therefore recommended to shut down non-essential startup applications and unplug external storage devices to allow the program to focus on internal files. It is also a good idea to schedule the scan for times that you will not be using your computer for other purposes.
To enable Avast’s Boot Scan, first you have to launch the antivirus program and then select the settings menu. Select the Protection tab from the settings menu, and then click on the Boot-Time Scan tile. You can select whether you want to run a full or a short scan, create new definitions, and also set what will happen after a threat has been discovered.
