This key seems to be part of Avira.What do you mean by unusable?

 

Do not touch registry keys if you dont have issues.

When I run CCleaners Registry cleaner I always get the unused extension {80b8c23c-16e0-4cd8-bbc3-cecec9a78b79}. I go fix all, then when I CClean the computer again after browsing or before shutting it down. That unused extension {80b8c23c-16e0-4cd8-bbc3-cecec9a78b79} shows up again in the registry cleaner. I'm just wondering why it's an unused extension, at least as defined by CCleaner. When I left click on the file it gives me the option to open it in its location. Regedit.  In RegEdit it says Name: ab(Default)     Type: REG_SZ    Data: (value not set).   I'm not sure what all that means, I guess the Reg_SZ is some kind of 'readable' document or something. I'm not to savy yet on programming, but I would like to learn more about it. Anyway, that's what I gather unusable means, the CCleaner's definition of the file anyway.

That might be an adware extension. Search in all your browsers for malicious add-ons or toolbars and remove them from the browsers.

 

Also find any irrelevant programs were installed on your PC through Control Panel.

If you are using Avira,do not touch it.
 

Bleeping Computer DOES NOT recommend the use of registry cleaners/optimizers for several reasons:

  • Registry cleaners are extremely powerful applications that can damage the registry by using aggressive cleaning routines and cause your computer to become unbootable.

    The Windows registry is a central repository (database) for storing configuration data, user settings and machine-dependent settings, and options for the operating system. It contains information and settings for all hardware, software, users, and preferences. Whenever a user makes changes to settings, file associations, system policies, or installed software, the changes are reflected and stored in this repository. The registry is a crucial component because it is where Windows "remembers" all this information, how it works together, how Windows boots the system and what files it uses when it does. The registry is also a vulnerable subsystem, in that relatively small changes done incorrectly can render the system inoperable. For a more detailed explanation, read Understanding The Registry.
  • Not all registry cleaners are created equal. There are a number of them available but they do not all work entirely the same way. Each vendor uses different criteria as to what constitutes a "bad entry". One cleaner may find entries on your system that will not cause problems when removed, another may not find the same entries, and still another may want to remove entries required for a program to work.
  • Not all registry cleaners create a backup of the registry before making changes. If the changes prevent the system from booting up, then there is no backup available to restore it in order to regain functionality. A backup of the registry is essential BEFORE making any changes to the registry.
  • Improperly removing registry entries can hamper malware disinfection and make the removal process more difficult if your computer becomes infected. For example, removing malware related registry entries before the infection is properly identified can contribute to system instability and even make the malware undetectable to removal tools.
  • The usefulness of cleaning the registry is highly overrated and can be dangerous. In most cases, using a cleaner to remove obsolete, invalid, and erroneous entries does not affect system performance but it can result in "unpredictable results".

Unless you have a particular problem that requires a registry edit to correct it, I would suggest you leave the registry alone. Using registry cleaning tools unnecessarily or incorrectly could lead to disastrous effects on your operating system such as preventing it from ever starting again. For routine use, the benefits to your computer are negligible while the potential risks are great.

Ok, Thanks NarenXp, I understand that changing the Reg can have bad consequences, back in the day with windows 95, I did some 'cleaning' of the registry that caused me to have to do a total reinstall/restore on the HP Pavillion, lol. I'm just looking at a more thorough explination of what that file and it's extensions/lables mean. I've read a bit about them, but would like an 'expert' or at least someone who has more knowledge to explain what these: Name: ab(Default)     Type: REG_SZ    Data: (value not set), mean. And how they operate within the system.

 

And thanks Special Techie for your comments, I think it is an Avira extension of some kind, I'm just more curious about what it does.

Unless the number of unused extensions is causing trouble, leave them alone. If an AV scan does not pick them up as threats, walk away. Never take obligatory notice of any cleaner program, they are guides not gospel,. CC may be god but it ain't God. .Use your own judgement, if you do not understand it, leave it alone. The rule is - if it doesn't itch, don't scratch it.

 

With 53.7 GB of free space, although CC comes up with a huge list of unused file extensions, the situation is far from critical.

Microsoft support policy for the use of registry cleaning utilities

...Windows continually references the registry in the background and it is not designed to be accessed or edited. Some products such as registry cleaning utilities suggest that the registry needs regular maintenance or cleaning. However, serious issues can occur when you modify the registry incorrectly using these types of utilities. These issues might require users to reinstall the operating system due to instability. Microsoft cannot guarantee that these problems can be solved without a reinstallation of the Operating System as the extent of the changes made by registry cleaning utilities varies from application to application...Microsoft does not support the use of registry cleaners...
