Try removing PTP.

Still would suggest you to open a case with symantec.

See if this helps:

I do not know this articles. Thanks Vikram and Prachand.

Hi Prachand... that's exactly the problem I have: If I disable the ADC, everithing works fine, but I need the ADC.
Thank you for the information, we'll be waitting for a Symantec solution.

Is there any fix for the problem? Of course without moving the ADC rules/policies

 Did you try the workarounds form the above article? If so were they successful? This might be helpful to other users who are experiencing the same issues.

Possible Workarounds

• wininit.exe is one of the critical startup processes that can be blocked--try adding it to the excluded list of the ADC rule
  NOTE that wininit.exe is a "caller process" and as such must be excluded at the topmost level of any ADC rule set.
  e.g. you want to allow wininit to launch other processes, not "allow wininit to launch wininit".
• modify the ADC policy to "log only" and examine logs for additional processes that are matched during startup--try excluding those processes.
• ... or remove environment variables from ADC rules (or explicitly spell out paths including those variables)

The blue screen errors may persist despite these work-arounds. In this case, disable Application and Device Control until a satisfactory solution can be found.
