A tiny program is in the zip file attached. SEP12 won't take it as a virus.
It looks like a Excel file, but when double click on it to run, an error message will occur. And then everytime you restart the PC and run some program like Outlook, a same error message occurs. But if you just click "OK" to close the messge box, appears nothing happened. You can continue doing everything, But you have to meet this error message everytime you start your system.
But things can't be that simple.
This tiny program will generate two folders with random folder name to the path %appdata%, and write a registry value to "HKCU\softwares\microsoft\windows\current version\run", and monitor this registry value not been deleted.
That's so far I know about this tiny program.
What does this tiny program propose to do? and how to remove it from system thoroughly?
