Summary
Trojan-Downloader:W32/Agent.D is typically found on certain malicious sites. When activated, it downloads an EXE file from a website and saves it into the root directory of the C: drive. The downloaded file is then run.
Removal
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
Technically. Agent.D's executable file is an HTML Application (HTA file). This file type is normally run by the MSHTA.EXE application, a program that comes standard with Windows.
While it is running, Agent.Dhides its window from the user when it is running by resizing the window to a zero size and preventing it from being visible in the Taskbar.
The trojan also drops a file named CMD.BAT into the root directory of the C: drive. This BAT file is used for cleanup purposes only: it deletes the trojan's file from the hard disk.
