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.

The antivirus lights up saying I have a JTI/Suspect. 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.
