Me being the dullard I am, perhaps I clicked on a download link that had not been updated.
The download link on Electrum.org is always up to date, so if you downloaded it from the official site, then this would not have happened. I am assuming you didn't bother to verify your download with the developer's PGP keys prior to installing?
There is no scenario in which Electrum will automatically generate a wallet with an address in the file name. The only two remaining options are that either someone else put it there (meaning you downloaded a malicious copy of Electrum or a malicious wallet file by mistake), or you put it there without realizing what you were doing (meaning that you must have copied it from somewhere else first - it's not a Coinmama deposit address?).
I think it's obvious and well established, to all. I didn't know what I was doing right from the start. I didn't verify the download and, therefore, it's very possible I did download a malicious copy/wallet file. I wouldn't have any way of knowing that unless I verified it which I didn't. (Mistake #4) As I stated in another reply, I did nothing other than enter my password into the field when prompted during set-up. What puzzles me is why is the bc still in the same place and not been moved after almost two years if the objective was to steal it?
Private keys were mentioned earlier. In the Electrum file I have a list of about 30 private keys that look like this: "bc1......" : "p2wpkh : [numbers and letters]", Does the possibility exist the bc can be accessed by using these? I was thinking I could delete everything Electrum I can from this PC and download a verified wallet but that would only create a wallet completely separate with no connection to my bc, correct?
