There are Bots here around in this forum which obviously contain malicious Code.
eg this thread here:

The .rar archive contains a compiled .exe and the source-code.
If you take a look at line 316 in CommonFunction.au3 you see this:
Code:
Func Setting1() Run("KurzickFarmingBot.exe" ,"","workingdir") EndFunc ;==>Runx86VersionIfNeed
I didn't decompile the KurzickFarmingBot.exe because im pretty sure there IS Malware inside!
So just be careful when you download anything here ... take a deeper look in ANY included file before you gona start such ****.
Take care!
