suddenly, it asked me whether I wanted to connect to servers automatically or manually,
One thing: that prompt will pop-up if "
auto_connect" isn't set in your config file or the actual "
config" file is missing.
Given that, if your wallet(
s) are in the default location and not affected, it's just your config file that's somehow deleted.
Not much of an issue if you remember your settings since it looks like not caused by Electrum.
If everything is missing, it has something to do with the whole electrum datadir.
This info will be useful for you to deduce what happened:
- Electrum's config, default wallet directory and other datadir files are stored in your %appdata%/electrum folder if you're using the "installer" (setup) or "stand-alone" version of electrum.
- On the other hand, if you're using the "portable" version, its saved in "electrum_data" folder in the same directory where the portable executable is.
The wallet would be affected if the whole datadir is missing unless the wallet file is on another directory.
Just to add, I have Malwarebytes and Norton 360 -- both of which I have been using for over 1+ year.
The config just contains JSON encoded Electrum settings, it's highly unlikely that an AV would flag it.
