This type of trojan contains one or more malicious programs, which it will secretly install and execute.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.

Security programs will sometimes unintentionally identify a clean program or file as malicious if its code or behavior is similar to a known harmful program or file. This is known as a False Alarm or False Positive (FP).
For example, 'tmp.edb' and other '.edb' files stored at the location 'C:\WINDOWS\SoftwareDistribution\DataStore\Logs\' may be unintentionally detected as malicious by various security programs.
In most cases, a False Positive is fixed in a subsequent database release; updating your F-Secure security product to use the latest database is enough to resolve the issue. If you suspect a detected file may be a False Positive, you can check by first updating your F-Secure security product to use the latest detection database updates, then rescanning the suspect file.
After checking, if you believe the file or program is still incorrectly detected, you can submit a sample of it to F-Secure Labs for analysis and correction:
If you are positive that the suspect file is safe and you want to continue using it, you can exclude it from further scanning by the F-Secure security product:

Microsoft provides enterprise-level instructions for excluding files from scanning by antivirus software:
A Trojan-Dropper is a type of trojan that drops different type of standalone malware (trojans, worms, backdoors) to a system. It is usually an executable file that contains other files compressed inside its body. When a Trojan-Dropper is run, it extracts these compressed files and saves them to a folder (usually a temporary one) on the computer.
In many cases, Trojan-Droppers also drop and execute other files designed to display games, images or messages, which serve as decoys to avert attention from malicious activities. For representative examples of Trojan-Droppers, see the following descriptions:
