Microsoft send out a warning that Windows 7 patch KB4493472 is causing trouble with various anti-virus tools. Distributed as part of this month's Patch Tuesday rollout, the update causes Avast, ArcaBit, Sophos, and Avira antivirus software to fail to start of become unresponsive. Microsoft is working on a fix an ETA is not known.

In a separate statement, McAfee claims Windows 8.1 and Windows 10 devices may also be impacted.
“Changes in the Windows April 2019 update for Client Server Runtime Subsystem (CSRSS) introduced a potential deadlock with ENS,” McAfee says. “McAfee is investigating this issue and will resolve it in a future update. A Proof of Concept (POC) build to test a fix is currently available. Escalate a Service Request to Technical Support to obtain the POC.”

The workaround, according to the McAfee, is to “disable any access protection rule that protects a service.”
