Is this a virus?

Hi, I’ve been trying to build a BartPE rescue CD this past week and one of the plugin has been detected as Win32:Trogan-gen {Other} as of today.

Plugin’s website: hxxp://www.bootcd.us/BartPE_Plugin_Details/212/ShutdownGUI-v1_0_2.html
Dowloading the cab file will invoke the web shield alarm.

Virustotal result: http://www.virustotal.com/analisis/6f5a963059641636de74cb6a756d9431

Should I be worried or is this a false alarm?

Most of the detections object to the way the file is packed, so considering where it came from, my money would be on a false alarm. Submit the file to avast! as described here:

Thanx for the help. I’ve sent an email to virus@avast.com to fix the possible false positive.
