Gamecheater doesn’t use another process/driver. I’ve setup new Win7x64 installation with all updates in Vmware, then I’ve installed and updated Avast(6.0.1000) and rebooted to enable sandboxing. Then I’ve launched Gamecheater in sandbox and verified that it’s able to find specific location in another process and change its value. Clearly, Gamecheater is able to bypass Avast sandbox protection. Hopefully you are going to fix this soon.
