We also just started detecting JS/Kryptik-BPH on all of our ESET Endpoint Antivirus ver 7.2.
We rolled back today's updates on a few endpoints and they stopped detecting. We think there's a problem in today's updates causing a false positive detection of JS/Kryptik-BPH.
We contacted ESET Support but haven't heard any confirmation of the problem to when to expect updates.
