Trojan-Downloader:W32/Kavala contacts a remote server and downloads additional files onto the affected machine.
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.
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.

Trojan-Downloader:W32/Kavala variants are distributed via file attachments to email messages. The malware itself is a Windows executable program compressed into a ZIP file that is attached to the email messages.
Both the ZIP file and the contents of the email follow typical social engineering patterns (e.g, using file names such as RE: Payment Pending or RE:Attachment Shipping Document) to deceive and lure users into extracting and running the attached program.
When the trojan-downloader program contained in the ZIP file is extracted and run on a user's machine, it will attempt to contact a remote server and download additional files onto the affected machine.
