Summary

Trojan:W32/DelfInject.gen!H is a generic detection for malicious files that arrives together with a special encapsulation code or program.

Security programs use generic detections that look for broad patterns of code or behavior to identify similar programs or files. If you suspect the file was incorrectly detected, go to: Removal: Suspect a file is incorrectly detected (a False Positive)?.

Removal

Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.

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.

Technical Details

The malicious file is embedded in this program and utilizes several protection mechanism such as anti-debug, encryption, virtual machine detection and other related anti-antivirus techniques. The program may also inject the stored malicious file into a legitimate process thus hiding its own process.The majority of malware that use this technique are Trojan-Downloaders; however, we have also seen it used by backdoors as another level of protection.
