accelfix vs. cheesefix

I recently had to format my pc and install my windows again, therefor I lost my mousesettings etc.
I downloaded all the usual stuff (accelfix, mouserate changer), but after I tried accelfix.exe, AVG said it's a trojan. Even though I tell AVG to ignore this, the accelfix wont work at all. I know it's not a trojan for real since my Avast didn't complain about it (I switched to AVG since it uses less memory).

Now my question is, what stuff should I enable from cheesefix and what not? And is there an other way to disable windows mouseaccel the same way as accelfix does it? Or is there a way to get accelfix working even with AVG on? Thanks in advance.
