Kaspersky says Minecraft Launcher is a Virus

The Minecraft Launcher dissapeard over night, so i reinstalled it. Every time i tried to install it my
antiviurs (Kaspersky) warned me about an virus called ´´Trojan.Win32.Vimditator.aena´´.
I downloaded the offical launcher from the Minecraft.net website. I tried to install it couple times and every time a warning poped up. I created an exeption in the antivirus and it worked again but every time i restart my computer the program (Miencraft Launcher) deletes it self, i dont know if its the antivirus. I linked the file from the log of its removal down below.
(its in German)
I hope you can change something, i never had these problems before.
