The affected devices malfunctioned, and the update provoked a blue screen of death (BSOD), which referred to problems with IDSvix86.sys and IDSvia64.sys. In addition, some users complained about an arbitrary reboot of the servers, but did not indicate which OS they were running. Some victims reported that the problem affected dozens of machines in their organization, while others wrote that they had problems with more than 10,000 systems.

First, users fixed the problem on their own (for example, rolling back to a previous version of Symantec Endpoint Protection helped), and then finally what happened reacted the developers. The updated version, 2019/10/14 r62, fixed the bug, and now the developers recommend that all victims arrange it as soon as possible.
Symantec did not specify which specific versions of Windows were in conflict with the problematic version 2019/10/14 r61, nor did they begin to give any figures regarding the number of victims.
