Restoring trackpad to original I messed up with my trackpad settings. I am also using bettertouchtool.

The problem is three finger drag has completely stopped working. None of trackpad settings in system preferences or options under accessibility are helping. 

Is there any way I can reset trackpad settings to original, the way it came with factory. I tried resetting PRAM, not helped. Any way to get back the default trackpad settings.
this is what I did:


uninstalled BTT
entered in Terminal mdfind -name bettertouchtool
entered in Terminal sudo rm -rf /whatever


went to /Library/Preferences


removed .GlobalPreferences.plist


went to ~/Library/Preferences 


removed .GlobalPreferences.plist
removed com.apple.AppleMultitouchTrackpad.plist
removed com.apple.driver.AppleBluetoothMultitouch.trackpad.plist


Finally I did a PRAM reset (Reboot, immediately hold alt/opt+cmd+P+R and hold these keys until the computer restarts and you hear the startup sound for a second time]

Frankly I got this by hit &amp; trial, I didn't knew what to do, so I did all at once.  After it restarted my trackpad was back like again. Maybe someone can edit this answer to make it perfect. Thanks :)
