What is Checked?
The following table shows you what areas of the registry AVG Registry Cleaner checks during the full scan. You
can select from these during the user-defined scan.
Area
Description
Audible Signals
For certain system or program events such as error messages, sound files are
played. These are played by accessing the corresponding entries in the registry;
however these entries are invalid once the sound files no longer exist.
Startup Programs
Many programs start automatically together with Windows (e.g. virus scanner).
This takes place via entries in the startup section of the registry. When such
programs are uninstalled, these entries are often not deleted.
File Types
Entries in this area of the registry link one or more file extensions (e.g. .txt or .doc)
with various information (such as the program that should be used to open them).
Such entries can become invalid through the uninstallation of programs, for
example.
Database Drivers
During installation, some programs store entries on database drivers and data
sources in the registry. These entries can become invalid through the uninstallation
of these programs or the moving or deletion of individual data sources. Often,
invalid entries are created during installation itself.
Common Files
This part of the registry contains references to files and program libraries (DLLs), to
which several programs normally require access. When such programs are
uninstalled, these entries are often not deleted.
Help Files
Many programs record in the registry the location of their help files. When such
programs are uninstalled, these entries are often not deleted.
Installed Programs
Every program leaves behind an entry in this area of the registry. The list of all
programs in the Control Panel is compiled from these entries. When programs are
uninstalled, these entries are often not deleted and inconsistencies arise in this
list.
Program Settings
Each program installed on the computer can create entries with program-specific
information in the registry (e.g. data or program paths). When programs are
uninstalled, these entries are often not deleted.
Program Extensions
This area of the registry contains references to extensions such as audio and video
