Think it's too late now, but hoping that someone out here can understand what needs to be done or reported to stop this scam. Am a newbie, had a 2 year old version of Electrum, opened it up to transfer 0.099 BTC to an exchange wallet, then before the txn completes, a pop up insists on installation of so-called version 4. it updates and completes the transaction (id# ccc3f772dad44e406441c835872fe1b444bee5498e13b7aa102fd99bc8643c6c) with an address (1MbomqWZxDts164kL9cdcinbhWZ7U6F9m5) that was definitely not mine.

Uninstall Electrum, download from the proper .org address, and try installing it and still the AV software insists the .exe is infected. I understand I've lost the BTC for good, but is it possible to report the offending transaction details anywhere? Thanks in advance. Will likely never use Electrum again after this.
A friend in Sweden got the same. "Upgrade to Electrum 4.0" (and let us steal all your money). electrum.org should maybe have a warning for this but they have no adress where I can contact them...
