Choose the program you want to use to open this file!!

Hello,

Everytime I restart my laptop, I get this pop up "Choose the program you want to use to open this file" for a file that has no extension, or at least the extension of the file isn't shown. I tried opening the file with notepad and get some sort of list with the title "Interface List".

I checked my startup folder and it was empty.
This problem only started a few days ago, and I can't recall doing anything different other than installing Symantec Endpoint Protection and running a full scan.

Any suggestions? I can upload print screens if necessary.

Regards,
numhum

The start-up folder will only show user-defined start-up apps. Open msconfig (Start -> Run -> msconfig.exe), go to the start-up tab and see if there is anything you don't want to run at start-up. But be careful, some important processes may look unfamiliar. Better to Google those unknown items first. But I am sure that all legitimate entries are well-documented on the web.

Nothing looks odd, whats there is the following

Google Desktop
Adobe Acrobat
Adobe Reader and Acrobat Manager
MobileMe
DefaultSettingEXE Application <<< The only one that looked weird?!
Microsoft Office 2010
HpqSRmon Application
Nitro PDF Printer Monitor
QuickTime
Java(TM) Platform SE Auto Updater 2 0
RealPlayer (32-bit)
Catalyst(R) Control Center
hpwuSchd Application
DivX Update
iTunes
Symantec Security Technologies
Windows Live Messenger
googletalk
Skype

When I open the file with notepad it says the following:

Umm the thing is I dont know the file type, it doesn't say, it just gives me the name of the file without the ".extension" part
