This trojan downloads an additional file from a remote server.
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.
Trojan:W32/HeurFu.gen and a number closely related detections (see More below) identify a file named report_082011-65_pdf.exe, which is being distributed to users in zipped files as email attachments.
On execution, the trojan creates the following temp file:
The trojan-downloader also creates a number of registry entries.
Then it attempts to download a file named blood.exe from a remote server. The downloaded file appears to be a Zbot variant.
A number of closely related detections identify the suspect file report_082011-65_pdf.exe. These detections use the naming format:
For example:
