I'm compiling this programm with g++ filename.cpp : https://pastebin.com/yjp65SZj This code is just an simple console app (input some numbers, output amount of numbers wih last digit = 0) After it Kaspersky something like shows it: "Found VHO:Trojan-Spy.Win32.KeyLogger.gen in a.exe”. If I compile something simpler, as "Helloworld”. there are no warnings. P.S. Если что, я и на русском понимаю.
