Trojan.Java.Agent.I is a trojan-dropper written in Java. On execution, the malware drops and runs an executable file.


  • Restart the system in Safe Mode.
  • Delete all files from the default temp folder.
  • Delete the following Registry entry:
    • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components\{F4C1E312-9D6A-7ED3-E25E-E8C403C69C4C}
  • Delete the JAR file containing the Java class file that was detected by the security program.
  • Reboot the system into Normal mode.
  • Finally, run a full computer scan with F-Secure Anti-Virus to repair any remaining files.

A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:

  • Check for the latest database updates

    First check if your F-Secure security program is using the latest updates, then try scanning the file again.

  • Submit a sample

    After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.

    Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.

  • Exclude a file from further scanning

    If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.

    Note: You need administrative rights to change the settings.
