Threat description




The file or program appears to be designed to install (or 'drop') a second file; the dropped file would have triggered a detection already available in our detection databases.


Automatic action

Once detected, the F-Secure security product may either automatically disinfect the suspect file or prompt the user to select a desired action. For more information, see: Support Community article: Automatic actions for viruses also used for suspicious items.


If in doubt, or in cases where a legitimate file is suspected to contain malicious code, please send a sample to F-Secure Security Labs via the Submit A Sample (SAS) for analysis. In some cases, subsequent analysis may determine the file is a False Alarm or False Positive. The relevant detection will then be modified to ensure the issue does not reoccur.

Technical Details

A program that is identified by a detection using the format 'Dropped:[variant]' indicates that the program was identified by a Heuristic Detection that identifies files with characteristics or behavior similar to known malware. The detection name may also include information about the type of program being dropped, such as:

  • Dropped:Trojan -The file dropped shows trojan-like characteristics.
  • Dropped:Adware -The file dropped shows adware-like characteristics.
  • Dropped:Generic -The file dropped shows general malware-like characteristics.
  • Dropped:Application -The file dropped appears to be an application that may introduce security risks (riskware).
