Miner I downloaded only from here. After I scanned the system the anti-virus Dr.Web cure it program, everything became a fine.
Now the hashrate on equihash = 420-440 H/s. So you look after yourselves.
Guys, I can confirm EWBF is infected with miner - my windows just detected it. I used Dr Web, as advised previously, to cure it. Now my EWBF is clean, there is no miner in it. There is however another problem - it's not mining any more. Any ideas?
Try to download other miner. I recommend to use miner ZM 0.5.8. It is very good program for mining of Equihash.
