Can't fix the Somoto.BetterInstaller with Spybot!

[Jess37]

Okay so I did a scan with spybot because my informatic teacher told us to try that at home. So I had a lot of problem to fix so they all got fixed except Somoto.BetterInstaller. It says "some problem couldn't be fixed; the reason could be that associated files are still in use (memory). This could be fixed after a restart. (...)" but after the restart it said the same so... I don't know what to do anymore... The 2 things under somoto.betterinstaller are (SBI $B8A7F4F7) root class HKEY_LOCAL_MACHINE_\SOFTWARE\Classes\sdp and the second one is the same except that at the end it's \sdp (64 bit)

Thanks alot!
