Trojan.Iframe.BMY, Trojan.JS.Iframe.CVT, Trojan.Iframe.BZW


Trojan.Iframe.BMY (and the similar Trojan.JS.Iframe.CVT and Trojan.Iframe.BZW detections) identify webpages that contain a suspicious hidden iframe appended to the end of their HTML code.


Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.

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

The suspect iframe appended to the HTML code contains either:

  • A link to a website hosting a PHP script named "counter[space inserted].php", or
  • The iframe name 'Twitter' and a link to a HTML page located at a random web address

In the event that the link or PHP file referred to in the iframe is in fact legitimate, please submit the relevant details (and a copy of the PHP file) to our Labs via the Submit A Sample (SAS) to check as a False Positive.
