Currently Kaspersky is in the middle of creating a patch that basically applies the registry key entries for the systems still affected. Below are the entries that can be removed in order to apply the new database update released:
REG DELETE HKEY_LOCAL_MACHINE\SOFTWARE\KasperskyLab\protected\AVP80\profiles\Scan_Startup /f
REG DELETE HKEY_LOCAL_MACHINE\SOFTWARE\KasperskyLab\protected\AVP80\profiles\Scan_Quarantine /f
REG DELETE HKEY_LOCAL_MACHINE\SOFTWARE\KasperskyLab\protected\AVP80\profiles\Scan_Objects /f
REG DELETE HKEY_LOCAL_MACHINE\SOFTWARE\KasperskyLab\protected\AVP80\profiles\Scan_My_Computer /f
What these entries do is prohibit the startup scan from initializing (which is what ultimately locks up these machines due to the definition update).
When the above entries are executed, a new update will apply to the Kaspersky UI and will ultimately fix the issue caused by the bad update from yesterday.
We are in constant communication with Kaspersky to alleviate this situation and get it resolved for all parties affected.
