Hi.
Good day.
I uninstalled the Avira antivirus, deleted their files and I tried to 
reinstall the Avira but I can not to do this:
. Avira does not install saying only that it could not to be installed.
. Then I used Regedit.exe for to erase all Avira references
. There are 3 keys that could not to be deleted:
   Key "HKEY_CLASSES_ROOT\CLSID\{F6D90F11-9C73-11D3-B32E-00C04F990BB4}" 
not deleted (access denied or locked)
   Key "HKEY_CLASSES_ROOT\CLSID\{000C101C-0000-0000-C000-000000000046}" 
not deleted (access denied or locked)
   Key "HKEY_CLASSES_ROOT\CLSID\{BFE18E9C-6D87-4450-B37C-E02F0B373803}" 
not deleted (access denied or locked)
. I installed Avira Registry Cleaner for to erase all Avira references 
in the registry and thhese keys could not to be deleted.
. Using Regedit.exe I tried to change the access permitions for the keys 
and it was not permited.
Please, how can I delete these keys?

Hi Matej.
Good day.
I executed the "avira_registry_cleaner_en" twice (see the attach 
Clean.png) and the keys referenced below remains locked or with access 
denied (please see the attach Locked.png).
When trying to install Avira as advised by you I found out in its error 
log the message:
	"0x8007064a: Failed to install MSI package"
Does this message means that I can not install anything usinf msi files?
None software that I used for to remove the registry keys could to erase 
them.
