So I had an old electrum wallet with some funds in it. I have recently created a new electrum wallet on my iMac running MacOS Sonoma. The Electrum wallet was downloaded from their official website, I have double checked that. On 7th of March I have transferred those funds in this new wallet, address: bc1q99qq2awpvu72mrs7gng84dkzyxcxk3q5gfwkx8

Then the funds were transferred mysteriously on 9th of March, to an address I do know nor does it belong to me. The address is: bc1q5chaqcn56sk2fq29z3cl37n5pfzhh06e2gx5uz and the tx id is: 85918ae49e2e40ee1ec481be089bebf929f7769c4247e03c8856140df3c2f0d6

My computer is protected by a password and I'm the only one knowing the password. Also the wallet file was protected by a password and again nobody knows that password. I'm using ESET antivirus on my computer with real time scanning. So on the 9th of March, at 20:42 the transaction was initiated and my funds were transferred. I was not at home at that time, the wallet was closed. I have not shared with anyone that wallet nor did I use the wallet address on any website.

I know that probably the funds are lost for good, I'm just trying to find a reasonable explanation for this.

Any help is kindly appreciated. If any of you has any way of recovering those funds, I'm ready to split the 50/50 the entire amount (which was around 6K USD).
