I also have this problem too. I open several ticket with the Kaspersky Support and the problem is far from being completely solved. After i sent a few tickets about this problem, they asked to enable traces in the server to analyze what is going on, but they(the traces), didn’t have any info about what is happening. They also suggested to: disable the heuristic analyzer Install a cumulative critical update But this suggestions above were worthless due to the fact that, the problem is still happening. I’m almost begging here you guys, what should i do to fix this problem once and for all?
