VRDB takes time… all your executable files will be processed.

You’re messing VRDB with Chest (Quarantine). That three files are on Chest for backup purposes.

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 \Data\Integ\avast.int
So it’s not a backup utility, but a restore feature of avast.

This was asked before… but if you want to quickly create VRDB, just choose to ‘create it now’ and wait.
