lost BTC during use of electron cash

[Emgee]

Hello
I've went through the messages here but I didn't find my case..
So, what I did is installed the (I think) legit Electron Cash software from https://electroncash.org/
I put in my private BTC paper wallet key in the "sweep" menu.. and nothing much happened in Electron Cash
But a few seconds maybe a minute later I suddenly saw in the Electrum "watching only" wallet that my BTC balance changed to 0!!
A transaction had been done to an unknown (to me) BTC address.
Can anyone explain to me what had happened? 
Like I said, I'm pretty sure I installed the correct Electron Cash software, so it shouldn't have stolen anything.
regards
Mike

Did you check your balance from an online block explorer.

Try to check your balance from blockchain.info.

There is nothing to do. I didn't use Electron Cash so I don't have any information but my friend used it without any problems.

I think there is a virus on your computer which stole your coins.

so, you think it's not an electron cash problem, but my computer has been compromised?

Here on Bitcoinforum is a whole section with many electron threads. Maybe you can find help there.

Hope for you, that you only made a reversible mistake.

I think it must be about potential malware. I used android version oıf electron cash with no problem. Sent my cash to exchange. You need to have better spyware killer on your computer I guess.
