SETTINGS
The settings of VRDB can be changed by clicking on the icon in the system tray with the right mouse button. There are three options:
Note: there is no mention of which icon, on installation the VRDB icon '
i ' is separated from the main avast ' a ' icon (which has nothing to do with the VRDB), when the ' a ' icon is rotating it is scanning files.
You right click on the '
i ' icon to access the VRDB settings and the '
i ' icon rotates when then the VRDB is being generated. It is possible to merge both together, in which case right click the avast ' a ' icon, select VRDB and you can then access the settings. Once again when the VRDB is generating the icons split so the '
i ' rotates, once the VRDB generation is complete the icons merge again.
