Generic detections are broad patterns of code or behavior that are used by security software to identify programs or files. If you suspect the detected file was incorrectly identified, go to: Removal: Resolve a False Positive.
Based on the settings of your F-Secure security product, it will either automatically delete, quarantine or rename the detected program or file, or ask you for a desired action.
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 Positive. In most cases, a False Positive is fixed in a subsequent database release. If you suspect the detected file is a False Positive, you can:
Usually, updating your F-Secure security product to use the latest database is enough to resolve the issue. You can check by first updating your F-Secure security product to use the latest detection database updates, then rescanning the file.
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it to F-Secure Labs for re-analysis.
NOTE If the file was moved to quarantine, you will need to first collect the file from quarantine before you can submit it.
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.

This malware is discussed in further detail in the following Labs Weblog posts:
The downloader is known to be distributed to users via a malicious website (driveby download) or via an exploit.
When active, the downloader downloads an encrypted file on port 443 or 80 from:
where (encrypted file) is a defined string. This string is unique in every sample.
Once downloaded, the encrypted file is first saved in an allocated memory where it will be decrypted, then saved to a file in a temporary folder. The file will then be executed.
The encrypted file is encrypted with an RC2 encryption algorithm. The Cipher Hash that is used in the decryption is based on a defined string that is also unique in every sample.
