IADHIDE is NOT a virus or a harmful program.

We've added this description as we sometimes receive questions about existance of iadhide.dll or iadhide3.dll. These files are a standard part of the F-Secure Anti-Virus program.

However, iadhide.dll is sometimes detected to be "spyware" by some spyware detection programs - such as Adaware. In reality, iadhide is a F-Secure BackWeb component. F-Secure BackWeb is used to download virus signature database updates automatically to the client computer. This ensures that you will have the latest virus signature databases on your system all the time without having to worry about updating.


You can control the existance of iadhide.dll on your system by installing or removing the "F-Secure BackWeb" component. Please note that we do not recommend uninstalling BackWeb, as you won't be getting automatic updates any more.

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.
