F-Secure Anti-Virus detects a third party installation package as TrojanDropper.DOS.Utter as it was used to spread infected files in the past. But there exist a few innocent files packed with this installation package that are detected as well (for example a Mario game that is 66055 bytes long).
The original infected installation package size was 341211 bytes and it contained Win32.HLLP.Yai virus.
Allow F-Secure Anti-Virus to disinfect the relevant files.
