Trojan:Android/Qicsomos, Trojan:Android/Qicsomos.A


Trojan:Android/Qicsomos.A exploits concern raised over another application, Carrier IQ, to lure users into installing and execute it. On execution, Qicsomos sends out SMS messages and then uninstalls itself.


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

Qicsomos.A promotes itself as an application called .Detecteur de Carrier IQ,. a French term that translates to 'Carrier IQ Detector'. It claims to detect and remove a controversial application, Carrier IQ, from the device.

In 2011, Carrier IQ was a source of some concern for security researchers and privacy advocates, as the application was alleged to have been silently installed by telecom operators onto their customer.s devices and used to gather information, including data usage and location details.

Qicsomos.A essentially takes advantage of fears raised by this issue to trick users into installing it. On executing Qicsomos, the app sends out four SMS messages containing specified content to a phone number, then requests permission to uninstall itself.
