Summary

Trojan:Android/AVPass.C is distributed in the guise of a Clock app; while active however, it steals information from the device and attempts to uninstall or bypass security-related apps installed on the device.

Removal

Once the scan is complete, the F-Secure security product will ask if you want to uninstall the file, move it to the quarantine or keep it installed on your device.

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

Trojan:Android/AVPass.C is distributed in an app named 'Clock'. On installation, it creates several app icons in the device's App menu panel. The icons are named "system update", "360Antivirus" and "QQ"; the last two names refer to popular apps, but none of the icons actually lead to a program.

Clicking any of the icons silently starts the trojan in the background, while the newly created app icons are deleted. Meanwhile, the trojan harvests the following details from the device:

  • SMS message and calls log
  • GPS location data
  • Contacts data
  • Stored photos
  • Phone's recording data

In addition, the trojan checks to see if any security/antivirus apps on an internal list are installed on the device. If found, the trojan requests for user root privileges in order to uninstall the security/antivirus app, or bypass it by modifying its database to prevent detection of the app.
