New Avira Free Antivirus doesn't show up in the right-click menu

If you updated from a previous version of Avira Antivir to the new 2012 version, it could have happened that the entry from the right-click context menu to quickly scan files disappeared. As this a pretty useful shortcut to scan questionable files, you might want to get it back.

It's very simple:

1. Go to Control Panel > Programs > Programs and Features.

2. On the list of programs that appears, look for the Avira Free Antivirus entry. Select it and press Change at the top, or right-click it and select Change.

3. On the new window that pops up select Modify and press Next. The default settings are usually the best settings, so you might want to leave everything like it looks and press Next until the modifications are complete. When you pressed enough Next, simply press Finish.

4. The right-click context menu should now be visible again.

How to remove the "AMD VISION" entry from the right-click menu

When you right-click on your desktop or in a folder you will see an AMD VISION Engine Control Center (formerly know as ATI Catalyst) entry in your right-click menu which allows you to have a direct access to the AMD Vision Control Center and fiddle with your graphics card settings. If you find this annoying and don't use that function or you have other means to access it (like from the Start menu) you might want to wish to remove it.

Removing the AMD Vision entry context-menu entry:

1. Open regedit.exe. (Start > Run.. (alternatively Windows + R) > type regedit > press OK)

2. Navigate to:

HKEY_CLASSES_ROOT\Directory\Background\shellex\ContextMenuHandlers\ACE

3. Double-click on the (Default) key and rename the value data to whatever you wish or put a few dashes in front of it to disable it, as shown in the picture:

4. Changes take effect immediately. You can close regedit.exe.

Note: these steps are valid for any version of Windows.
