Summary

Briss is an spyware (intrusive advertising software) made by BlazeFind. It is usually installed to computers without any warning or notification to users. The main component is a BHO (Browser Helper Object) that creates a search toolbar in Internet Explorer's interface. The spyware is capable or auto-updating itself. It reports information about users' hard drives and operating system version to its maker, that is why we consider it a spying trojan.

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

Variant:TrojanSpy.Win32.Briss.H

The main Briss's file is an installer that drops 3 files into Windows System folder without any notice to a user. These files are:

a.exe
jao.dll
bridge.dll

Then the startup key for the bridge.dll file is added to the following key:

[HKLM\Software\Microsoft\Windows\CurrentVersion\Run]

This allows the dll to be loaded in memory during every Windows session. The dll file works from under Explorer.exe (main Windows component). The spyware connects to the www2.flingstone.com site and reports certain data. It can also download and install upgrades for itself.

When uninstalling Briss from Control Panel -> Add/Remove Programs, please select 'Bridge' and then click 'Change/Remove' button.
