So I gave a Google search of the two servers you've mentioned in the third post of this thread. A Google search of "exs.ignorelist.com phishing" resulted in a report from MalwareBytes, and I don't believe it's a coincidence.
Something smells fishy to me here. I've taken a look over all the posts on this thread and, according to #4, the address 34Y6nb5SRxAGkozUpyKa59Qq7f87acC98s, which OP confirmed was one of the addresses he used as an input in one of his transactions, is listed right next to its private key on https://bitkeys.work/?page=725.
I'm confused, to be honest.
Edit: apparently the website generates a random private key for the richest wallets, hoping to collide with the address.. I thought it was one of these "all BTC private keys" websites.
Still, the Google search I've done linked me to the report above. Hence, OP might've downloaded an infected Electrum wallet..
Edit 2: I've done another search for the second server MalwareBytes categorized as a "Phishing". According to this link I found,
In other words, OP has fallen victim to a phishing attack... Press CTRL + F and look for "exs.ignorelist.com" and "endthefed.onthewifi.com", you can find them in the code above. I'm sorry, OP.
Please take measures ASAP to secure all your funds before they'll steal more out of your wallets..
Considering your wallet is compromised, I can assume you might also have other compromised softwares installed on your computer. Therefore, I'd suggest switching the internet off on the computer you've got Electrum on (or plugging out the Ethernet cable), backing up everything important (don't forget to backup the wallet.dat files!!!!) and doing a fresh, SECURE complete wipe out and reinstall of the operating system.
If you connect your computer to the internet again after reinstalling the OS, please make sure the software you install is legit.
We're talking about very large amounts at stake, so taking appropriate measures against phishing might save you from another disaster. I really wish I could've helped with the recovery of your funds..
Apparently my attempt to do an extensive research of the MB detection from the first few posts of the thread turned out to be just a shitty failure in the end. Will try to look up the change path scenario Lucius has linked and anything useful will be posted on the thread.
