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.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
More information on scanning and removal options available in your F-Secure product can be found in the Help Center.
