were to get off server files?

real virus or not? i dont realy risk it disabling norton for that

edit: i don't know about that patch.dll that you said.i just extracted the rar file and...the rest is on the image

code of patch.exe used to inject the dll, is posted in post pacific:

hxxp://www.postpacific.com/forum/viewtopic.php?t=2295

you can see if it's a virus or not...


;Static DLL Injection for MASM by Aphex

;http://www.iamaphex.cjb.net

;unremote@knology.net

;This uses code by Yodah and Freddy K



;What this does: It forces a PE to load a DLL everytime it is ran by

;patching the actual file. No other loaders or memory injectors are needed.



;How it does this: It opens the PE file, adds a section to the end of the file,

;alters the entry point to execute this section first. Then the new code loads

;a dll and jumps back to the original entry point where it runs as normal. ;)



;NOTE: you must add this linker option "/SECTION:.text,RWX"

;ml.exe /coff patch.asm /link /SECTION:.text,RWX /SUBSYSTEM:WINDOWS /OPT:NOREF

.model flat, stdcall
