/*

DLL OCCURENCY FINDER UTILITY
it simply searches in all running process for <DLL_NAME> occurency.

Very useful with malware detecting/removing. Imagine you
find a dll which you can't delete and you need to know
which process is running it...

coded by Piotr Bania <bania.piotr@gmail.com>

Sample usage:

E:\projekty\finddll\Debug>finddll jar50.dll

....
[+] Searching in ping.exe (PID=0x564) for module occurency.
[+] Searching in firefox.exe (PID=0xFC4) for module occurency.

[*] --- MODULE OCCURENCY FOUND ---
[+] jar50.dll found in firefox.exe (PID=0xFC4)
[+] jar50.dll base located at: 0x023c0000
[+] jar50.dll handle in process: 0x23C0000
[+] jar50.dll size of module: 0xD000 bytes
[+] jar50.dll path: C:\Program Files\Mozilla Firefox\components\jar50.dll
[*] --- PRESS ANY KEY TO CONTINUE ---
