Where did you get this "Electrum.lnk" I can't find this file on my Electrum wallet files in program files folder or in %appdata%
If you use the Windows installer, it creates .lnk files in the "Start Menu". For instance, on Windows 10, I have "Electrum.lnk", "Electrum Testnet.lnk" and "uninstall.lnk" in the following directory: C:\Users\YOURUSERNAME\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Electrum
If you use Standalone or Portable version, these shortcuts are not created.
As for the OP's original question:
Is bitdefender crazy and should i just restore the file ?
Bitdefender is "crazy"
It's most likely just a false positive... It's a known issue due to the Electrum devs using PyInstaller... If you have a look on
the electrum.org download page... and read the "Notes for Windows users":
Electrum binaries are often flagged by various anti-virus software. There is nothing we can do about it, so please stop reporting that to us. Anti-virus software uses heuristics in order to determine if a program is malware, and that often results in false positives. If you trust the developers of the project, you can verify the GPG signature of Electrum binaries, and safely ignore any anti-virus warnings. If you do not trust the developers of the project, you should build the binaries yourself, or run the software from source. Finally, if you are really concerned about malware, you should not use an operating system that relies on anti-virus software.
If you are 100% sure you downloaded from electrum.org and you have
verified the digital signature, then it should be fine to add an exception to your antivirus to allow it to run.
