Re: Block Firefox

I tried this before and it didn't work, though I had Block and Report ticked (Changed to just Block now) and I had *.firefox.exe in the executables area (changed to just firefox.exe now)

Though I don't know what 'Inclusion Status' means - Include or Exclude? I have it as Include

In the Subrules (which it says I have to complete) I have everything ticked except Delete under Operations, and under Targets I have Include, File Path and *.firefox.exe.

Hi @idsanalysts 

Thank you for your response. I think we have the solution now!

Under sub-rules --> targets I would recommend adding wildcard  "*"instead of mentioning the path of Firefox.exe.

Re: Block Firefox

Hi @idsanalysts 

I sincerely hope this resolves your query. However,in case you are interested in knowing how exactly that works, I have explained that in detail over here if you have time to read through it. Also, Include would be the right choice. You have got that right! Please let me know if it is still not working.

Re: Block Firefox

Hi,

I still can't get this to work.

I've tried the Access Protection policy with *Firefox* and the Options policy using the PUP and neither seem to work.

Re: Block Firefox

Hi @idsanalysts ,

Let us begin with the pic: Options Policy.jpg.

  1. Here, please remove the name Firefox from Exclusion by Detection name.
  2. Under potentially Unwanted Program Detections, Please add the File name as Firefox.exe.
  3. Now Kindly please save the policy.

Let me know how this goes! ( More responses follow for other policy screengrabs as well!)

Re: Block Firefox

Hi @idsanalysts,

Now Let us look into On Access 1.JPG and On Access 2.JPG

  1. This one looks like the Access Protection Policy (I am sure this does not belong to On Access Policy!)
  2. The File Name or Path mentioned needs to be changed to Firefox.exe

Checking further...
