Adware.Dropper is a family of installers that installs adware without properly notifying the user.
In order to be considered proper notification, bundled adware must have at least one screen that requires user interaction to accept the license agreement. The page should contain the names of any adware and a brief note about the implications it may have for the user. There should also be a link to a webpage where more information about the software is available.
Based on the settings of your F-Secure security product, it may block the file from running, move it to the quarantine where it cannot spread or cause harm, or ask you to select an action.
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.
The Adware.Dropper family contains files which are known to drop advertising contents, but are not categorized as Trojans. This could be custom built Wise Installers, or installers for a software which also drop ad contents onto the system.
