On November 26 the team of Bitcoin Gold published a critical warning on the official website of the coin stating that the link on the Download page of Windows Wallet and the file downloads on the Github release page were providing a suspicious file of unknown origin for about four and a half days.

As it was stated in the warning the users should presume that the files were created with malicious intent in an attempt to steal cryptocurrencies and/or user information. The file does not trigger antivirus or anti-malware software, but it does not mean that the file is safe.
If the file was used, the computer on which it was used should be addressed with extreme caution; the file should be deleted, the machine should be thoroughly checked for malware and viruses (or wiped clean), and any cryptocurrencies with wallets accessible on that machine should be moved to new wallet addresses immediately.

It is reported that the source code was not changed and the users who downloaded the source code to compile it themselves should be unaffected, but they are recommended to make sure if their local repository matches the current Github repo and be extremely cautious.
