Please be informed that the original threat might got removed by the AVG program. It is always recommended to scan the PC regularly using the AVG program so that the threats affecting your PC will get removed.

I have found at Microsoft:
Let AVG delete the threat, but note where it says the file location is. Go to that folder, open notepad and save a file as "SppExtComObjHook.dll".
After doing that, I restarted my PC and it seems like whatever was creating that file, was unable to do so because the fake one I saved was there instead. No more AVG popup, and hopefully no more whatever threat from SppExtComObjHook.dll.
