There have already been multiple threads/posts on here about exactly this issue. It started over 2 weeks ago.
The ONLY official place to download is:
https://www.electrum.org/#homeCurrently, the latest version is 3.3.3
AND you should
ALWAYS verify the digital signature of the downloaded file before installing and/or running it.For reference:
https://bitcointalk.org/index.php?topic=5095856.0I do not understand how it was possible to show this hint dialog, because my Electrum Wallet 3.1.3 is an original version. It seems like the DNS request has been redirected or something similar.
There was a flaw in the design of Electrum where it would just display the raw text of whatever "error" message was returned by an Electrum Server (including links!). Hacker set up a LOT (like hundreds) of "fake" servers that would send back the error message with link to fake update.
These issues have been resolved in (official) 3.3.3 version
