The file detected as 'Trojan.Win32.Starter.h' is not malicious. When run, it opens the setup dialog of GAIN's (former Gator) 'Magic Waterfall Screensaver'. We will consider moving detection to adware databases.
Depending on the settings of your F-Secure security product, it will either automatically delete, quarantine or rename the suspect file, or ask you for a desired action.
