How can I find out who the 2nd address belongs to and get my funds back into Electrum. I should have not gone with Electrum as they provide no support.
Well..you can never find that out unless someone has posted it somewhere.As I cross-checked with wallet explorer,no more addresses were found as part of the same wallet.I'm afraid you're not getting those coins back if in the worst case scenario your computer is being infected with a malware which auto copies a address as a string from the clipboard and replace it with the hackers bitcoin address.I can be completely wrong,maybe you should wait for expert opinions.
