Why do I receive a note that the file pagefile.sys / swapfile.sys cannot be checked?

If you have checked the system partition with the AntiVir Scanner, which is usually C:\, you could get the following message in the report file:
c:\pagefile.sys
[WARNING] The file could not be opened!
[NOTE] This file is a Windows system file.
[NOTE] This file cannot be opened for scanning.


This process is normal since it is a swap file of Windows.

You can find more information on Microsoft's web site.
