This type of trojan secretly downloads malicious files from a remote server, then installs and executes the files.

Automatic action

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.

Suspect a file is incorrectly detected (a False Positive)?

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 detection database 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

This malware will only affect a user who is browsing a malicious website, or a legitimate website which has been compromised. Unlike more straightforward trojan-downloaders, this malware does not directly download the malicious files itself, but rather redirects the user to malicious websites which perform the actual download automatically.Upon execution, this malware uses Iframe tags to redirect the user to the malicious websites:[...]/fxx.htm - Trojan-Downloader.JS.Agent.ckl[...]x.htm - redirects to ilink.html, flink.html[...]c.htm - Trojan-Downloader.JS.Agent.ckk These sites will then subject the visitor to a drive-by download.
