Aye, yesterday I downloaded and activated the WinAuth which was refered in the GW2 wiki for 2 step auth., first I seen nothing but today when I fired up my pc the console flashed in on startup, then in the background 2 malware / adware was installed, luckily I immediately found the new installations and removed anything connected to it, also the malware changed the default browser desktop icon’s startup arguments to load the delta-homes.com as a forced startup page.
I didn’t install or done anything else than installing the WinAuth from their official website, so if any1 else having the same issue we can prove the problem.
But the software is open-source you can find the code at https://github.com/winauth/winauth which would clarify it, except that the build date and the latest PR’s date for 3.2.10 out of sync, so waiting for responses.
