Those two programs are paid for products and not part of the Avast Free Antivirus and possibly not Avast Premium either, so may well be programs in their own right.
You don't say what program you have/had that you uninstalled ?
Certainly the Avast Secureline (VPN), so this may not be removed with the avast antivirus program.
Is there an entry for either of them in the normal Windows, Control Panel > Programs > Uninstall a program area ?
