A boot scan is an effective feature provided by many antivirus applications that can eradicate malware that is unable to be removed via normal methods. This kind of virus is able to be hidden in the boot sector or encrypt files, and is typically more difficult to remove than a normal runtime scan. It is essential to use an anti-virus that can perform an examination of the boot sector, as this type is not easy to spot, but also extremely dangerous.
Avast’s Boot Scan is an efficient method of identifying hidden threats. It can detect threats that are normally not detected by runtime scanning, and is capable of removing them without disrupting the running of Windows. It can take some time to run the scan because it will have to scan all the system files. It is a good idea to disable non-essential applications at startup and disconnect any external storage devices. This will allow the program to concentrate on internal files. You can also schedule the scan to run at a time when you’re not using your computer.
First, open Avast and then go to the Settings menu. Select the Protection tab in the settings menu. After that, select the Boot-Time Scan tile. You can select whether you would like to run a full or a short scan, install new definitions, and also set what will happen in the event that a threat is identified.
