Ok Patch b installed. I see in the changelog: We have fixed an error that prevented the automatic deletion of temporary files. reboot and BOOM, 21 GB cleaned. Thanks. Now, to fully understand situation: C:\ProgramData\KasperskyLab\adminkit\bases\cache Totally cleaned C:\ProgramData\KasperskyLab\adminkit\1093\.working\FTServer\f933651e-1f9c-425c-9be9-5cec8badad33.package and C:\Program Files (x86)\Kaspersky Lab\Kaspersky Security Center NOT cleaned, exactly the same as before, is this normal or is there something i can do with these folders? Thanks!
