    How do I check AVG antivirus for a download file?

    If you are trying to scan a downloaded file, look for a custom scan option, then select downloads or whatever folder/drive you downloaded it in.

  • Question
    How do I scan .jar files? None of these methods work for .jar files. I made a RAT infected .jar file and it wasn't detected.

    These methods do work for .jar files. However, keep in mind that they are not 100% effective. This is especially the case if you made the RAT file yourself and it has never been seen in the wild before.

      • Many anti-virus programs offer real-time protection as well as virus scanning. This means that the software will notify you when it detects that you are downloading a virus attached to a file or if a website tries to attack your computer with viruses.

      Warnings

      • Some programs that are designed to check a download for viruses can slow down your computer due to heavy CPU usage. Online virus scanners are a better option when you don't want to install heavy software on your computer system.
