Hello everyone, I am Dean.
Recently, many Minecraft server plugins have been affected by antivirus software on the Windows system, resulting in the inability to download or use jar, including LiteSignIn. This update involves re uploading the file (rebuilding and removing any content that may have been misjudged by antivirus software). Here are some ways you can try to recover files when you are unable to download the jar:
1. In the Windows startup menu, search for "Windows Security Center" and open the Security Center.
2. Open "Protect History" in the Security Center, find LiteSignIn in the list, and click "Restore Files" in "Actions".
3. Return to the download directory to find the deleted jar file.
Due to the fact that some antivirus software operates based on Microsoft's virus library, you may also be subject to misjudgment from other antivirus software. Therefore, this is only a recovery guide for Windows Security Center. Please adjust other software according to its own functions.
