dvpapi.exe and AVG

Hi all. I know that dvpapi.exe is not malware (from what I've read), but I disabled it since I have AVG installed, and I am trying to disable as much as possible in hopes of speeding my computer back up (it's been "hanging" quite a bit lately). My computer now seems to run a lot faster. Does anyone see any reason why I shouldn't completely uninstall dvpapi.exe, and it's associated software? AVG doesn't need it to run effectively, does it?

 

Hi Dr. M. Thanks for replying.
I have the whole program (Authentium), although I don't know how I got it. I was just concerned about deleting it, because I read that some antiviruses use the dvpapi process. I just wanted to make sure AVG wasn't one of those.
