Someone is adding code to my program. I feel insecure!

Post by Zofz »

I have detected this by chance, looking at the crash logs and having problems determining addresses inside library modules. So I have listed all modules ZofzPCB loads into its address space.

There are some extra modules!

Paths are pointing to the antivirus (see below). That is what I would call a virus - a program that is hooking itself to other programs. I can't believe it!

So I started to google my findings, and yes, they do it. Antivirus is a virus. It is manipulating my (and any other) program, slowing it down! Performing who knows what actions - could be sending some data over the internet or collecting user behavior.
That would not be my business, one can say, as the user has installed this software himself. But they do it as me, using my process ID! So how do I explain this to my users, especially if I don't know what exactly happens?

Here is someone collecting information about hooking, which I found on Github:
Someone else is fighting back: ... he-inside/

Check inside your own logs:
  1. pop-up the window's "RUN" dialog, by pressing [windows-key] and R
  2. enter %APPDATA%/ZofzPCB/ZofzDebugLogFile.txt and press return
  3. A text editor should pop up, showing the ZofzPCB log
  4. Search for a line of stars ***********************
  5. That is the start of the program. You will see some basic information about the program version, CPU, etc. Then below, there will be a list of modules. In my case, lines 5 and 6 show the antivirus hooked code.

Code: Select all
