Thank you for the reply guys! No malware on my pc, that's for sure. It was a error from there wallet, if you look at the print screen you can see that the transaction ammount was sent to the miners. It was somekind of buy in that moment or something that caused it or perhaps it's a scam. I do not know yet, but they are still having problems with there wallet as we speak and I have another 1.5 btc moved from them and it has been days since the transaction has not confirmed. I suspect he did a wallet rescan and he is trying to pull back the money I sent from the wallet because transcation is still uncofirmed but with a good fee so I dont see what else could be the problem.
Good to hear that they're doing something. It would seem like they are pretty fishy. I would recommend not using lesser name Bitcoin wallets, and use reputable wallets like Electrum. Preferably stay away from web wallets because you're trusting your money with other people.
