Removal

Automatic action

Based on the settings of your F-Secure security product, it may block the file from running, move it to the quarantine where it cannot spread or cause harm, or ask you to select an action.

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

The animated greeting card was installed on a hard drive and the uninstallation program for it was provided. But at the same time, the CARD.EXE file hiddenly dropped 3 adware/spyware files in Windows System folder:

HMEPGE.DLL
 HOTLINK.DLL
 IEBRW.DLL

These files are not malicious, they are adware/spyware components that help its makers to collect information about computer user's habits and provide him with appropriate advertisment. No personal information about a user is collected.

As these adware components were hiddenly dropped to computers without a user seeing and accepting a licence agreement, we consider the CARD.EXE file to be malicious. We added detection for this file into our anti-virus databases.

If you got the message mentioned above, please do not follow the link, do not download and run the CARD.EXE file.
