So, this past weekend I decided to send some BTC over to Gemini to withdraw and trade into Ethereum. This was this past Saturday night, December 9th. I access my desktop remotely via Teamviewer to get the coins out of my desktop wallet and sent over. The transaction completed successfully, I had to input my wallet password for each transaction for a total of two transactions for two bitcoin sent to Gemini at a rate of one each. When I came home after the weekend away from my desktop, which I kept running and no-one home at the time, I notice that my remaining balance was gone!? I checked the address the BTC was held which is 1AUyoMFrcjo4DybZiS2nZn6M4P5NfDsxho, https://blockchain.info/address/1AUyoMFrcjo4DybZiS2nZn6M4P5NfDsxho, and noticed that in the same block the remainder of my BTC was sent to https://blockchain.info/address/1Lmdg8LLBG8gK9QU7WZHDmVoupV9UF2y7G and partially to https://blockchain.info/address/1Kt4GBMumvH1vzKygeJuSixTQJLoJvA2d4 in another block, which I did not initiate!!! How could this have happened! I have heard of keyloggers/trojan horses in the past?? Is there something I am missing here or did my BTC get stolen? Any help or understanding would be appreciated.

Sincerely,
