F-Secure Virus Descriptions : Hacktool.Underhand

F-Secure Anti-Virus does not detect any virus by this name.

We've added this description because our support started getting queries from users who received an alert on this virus on their Macintosh OS X systems by Symantec Antivirus or Norton Antivirus.

This seems to be a false alarm from Norton.
