How the VRDB Works

[artificer]

I am new to AVAST but to my surprise after it finished creating the VRDB there was no noticeable change in the amount of free space on my disk.  So now I wonder how it really works and how trustable it is. Also I would like to know what files are going to be protected by it and where it is stored.

Thanks in advance

VRDB stores the necessary info to restore executables (*.exe, *.com) files.
VRDB is not a backup system, the stored information is very small (not the whole files).
Besides, only Win32 executables are processed.
The VRDB data are stored in <avast>\Data\Integ\avast.int
So it's not a backup utility, but a restore feature of avast.

Welcome!

As Tech says the VRDB isn't a back-up utility, it just stores enough information about the file to apply a repair if infected, for those files that it monitors.

the .com extension is for which type of files?

Executable file. Command.
