On one of my machines, Kaspersky has been deleting clients for both TEKcoin and Hyperstake for the last couple of weeks.
The machine was running Win10 using the defaults (I know, I know) so one obvious first step was to tighten that up, generally following these fairly standard guidelines:

Those changes appeared to work for a week or so, but then Kaspersky deleted the TEKcoin client without warning or explanation on both machines.
Today, on one of the machines, Kaspersky is finally identifying the reason for its action, but only for the Hyperstake client. It alleges that trojan.msil.coinstealer.hv is in the zip file.
That's all I know so far, and I've been holding off posting because the facts are so skimpy. Be careful though, especially if you are using the Windows ZIP file for either coin wallet.
