FAQ: boot scan

Previous pageReturn to chapter overviewNext page

If your computer is brand new, or has been protected by antivirus software until now, you can run the installation as follows.

However, if you have good reason to suspect that your computer has already been infected by a virus, it is recommended that you run a boot scan before installing the software.

BootScan: When you switch on your computer, your Windows operating system starts automatically as normal. This process is called booting. However, there is also the possibility of other operating systems and programs being launched automatically.

To scan your computer for viruses before Windows starts, G DATA provides you with a special bootable version in addition to the Windows version.


The BootScan helps you fend off viruses that have embedded themselves on your computer prior to installing antivirus software.

To do this, there is a special version of the software that can be run prior to starting Windows.

Booting from CD/DVD-ROM: If your computer will not boot from a CD/DVD-ROM, you can carry out the following procedure:

 1Switch your computer off.
 2Restart your computer. Usually you reach the BIOS setup by pressing the DEL button (or F2 or F10 as well depending on your system) as the computer boots up.
 3How to change individual settings in your BIOS setup varies from computer to computer.
To do this, please consult your computer's documentation.
This means that the boot sequence should be CD/DVD-ROM, C, i.e. the CD/DVD-ROM drive becomes the 1st boot device and the hard drive partition with your Windows operating system is the 2nd boot device.
 4Save the changes and restart your computer. Your computer is now ready for a boot scan.

How do I cancel a boot scan? If your computer displays the G DATA BootScan software interface instead of the usual Windows environment after restarting, there is no cause for concern.

If you have not planned to run a boot scan, just use the arrow keys to select the Microsoft Windows entry, then click Return. Windows will now start normally, without first carrying out a boot scan.

Booting from USB stick: If you use a USB stick as a boot medium, you can also select this as the 1st Boot Device.
