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.

The following details are general characteristics applicable to many, but not all, variants in the Waledac family.
Waledac spreads in an email attachment. Social engineering tricks are used to tempt the victim. Waledac spam frequently uses holidays and news headlines. For example, a fake Barack Obama websites was used as bait during the US 2008 Presidential Elections. Obama spam was also used during the US Presidential Inauguration.
Waledac is capable of receiving commands from a remote server. Commands include instructions on functions to perform (for example, update malware components or send information from the infected computer).Samples analyzed in the lab also downloaded Rogue antispyware applications. Waledac variants use lists of hardcoded IP addresses to determine where it sends harvested data. More recent variants can also update their lists from the remote command server.
The packers used by Waledac are different depending on the variant. Cryptor is being used as of January, 2009.
