This bug documents a problem with the Cylance AV Solution.

User report

GPGMail 2.6b2
OS X 10.11.1

I am currently using Cylance for threat detection on Mac and when using GPG Tools to sign outgoing messages, Cylance kills the gpg-agent due to "Exploit Attempt" specifically Stack Pivoting.

Workaround

  1. uninstall GPGTools
  2. install homebrew
  3. brew install gpg2
  4. re-install GPGTools but use "Customized install" and de-select MacGPG2

Since with homebrew, this problem is no longer happening, the issue is related to GPGTools MacGPG2.
