Why doesn't KES work in Safe Mode? [KES for Windows]

It is not possible to enable KES booting when Safe mode is running. However, booting in Safe mode can be disabled using GPOs or the local registry. It can be done by a local administrator. One of the ways to disable Safe Mode is described here.

Why are not all browser extensions blocked by Application Control? [KES for Windows]

Update task completes successfully but bases remain outdated [Kaspersky Security for Windows Server]

Problem In some cases, it is possible to run a database upgrade task on the KSWS/KICS/KESS host, but despite the upgrade task successfully completing, the databases are still out of date. Solution Most probably product operates in UpdateBlackListOnly mode. This happens in cases when product is activated with activation code and is unable to reach our activation servers.

KSWS spawns a lot of PR*.tmp files [Kaspersky Security for Windows Server]

Problem You might notice that large files named like PR*.tmp appear in C:\Windows\Temp. Cause This is known and expected behavior. When the product scans an object it creates a temporary copy, names it like PR*.tmp and places it in the temp folder.Once the scan is complete, this temporary file gets deleted. Large PR*.tmp files mean that some large objects are scanned by OAS (On-Access Scan) or ODS (On-Demand Scan). Solution In some cases there might be not enough sp
