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.
Technical Details
MailRuSputnik HomeSearch is a program that adds supplementary functionality to a web browser (also known as a Browser Helper Object, extension or add-on, depending on the browser in question).
It is typically distributed bundled with a legitimate program, alongside other such optional third-party software. As with most such programs, they may be unintentionally installed together with the desired main program.
On installation, the program is added to the web browser:
Adware.MailRu added as a BHO
It will modify the web browser settings for the search address:
Adware.MailRu alters the default search address
It may also alter the user's set homepage to display a page that looks similar to the legitimate MSN or Yahoo! pages, but contains more advertisements or sponsored links.
