Windows User Account Control

Lately when I boot up in Windows 7, User Account Control gives the following message:

 

"Do you want to allow the following program from an unknown publisher to make changes to this computer?

 

Program name:  win3909712120.exe

Publisher: Unknown

File Origin: Hard drive on this computer

Program location: C:\Users\myname\AppData\local\Temp\win3909712120

 

This message pops up several times after I deny the change, and each time the number sequence is different.  I have run Norton Internet Security multiple times but this message reappears each time I boot up.  Is anyone familiar with this message?  Is it something I should be concerned with?

Based on information from Bleepingcomputer (http://bleepingcomputer.com/startups/win.exe-8178.html ), it looks like it’s a piece of malware. Run Malwarebytes and visit Bleepingcomputer malware removal forums.
