I apologize for the delay in the response.
On Tuesday, one of our rollouts caused us to indirectly identify some Chrome and Microsoft files. Our engineers were quick to fix this and the file dispositions have been set to the correct value by Wednesday. Although a lot of files have been affected, I believe it should not have caused any major impact as the files will not be quarantined. One of Immunet features called Guard Rails will prevent it from quarantining signed files.
Feel free to send us an email at firstname.lastname@example.org if you have any questions.
