This morning I sent my Electrum wallet some BTC from coinbase and went on with my day. Came back 45mins later to find at the very same second I had initiated my receiving transaction, my wallet had also initiated (on its own) a send transaction to an unknown address before the funds were even available in my wallet. There was no way to stop it and my funds are now gone... Is this some sort of glitch in electrum's system, or is this signs of a compromised wallet?

Receiving transaction ID: 11ba4ba28dd4230c15781a1e8c755f5d9b89862612b7b6cf415bf4978e99375b

Sending ID: c40d8a10d51a1d54cdd989364513d8cdcaa5fc83711016c5ce3d2a0803ded67d

Any help would be appreciated......
