Well what I really wanted to know the most is if it pops up while you\'re not even touching your mouse or keyboard...
If you changed your .exe to .com like I said and it came back, then it\'s normal... ... Just delete the calc.com file. Don\'t worry, calc.exe came back on its own so the calc.com we made is now useless. That\'s why you can now delete calc.com. It\'s also just to reset what was in your old calc.exe, in case it has a keyboard shortcut and other hidden stuff integrated.
Still gotta make sure though... Can you right-click on calc.exe and choose "Properties" to see if there\'s any keyboard shortcut? The field (shortcut key) should be left blank in case there\'s something in there. Or to "None".
IF the calc.exe still pops up while you\'re not doing anything, then it\'s time for some hijackthis.

Do a system scan and save a logfile.
After the scan is over, copy all what\'s in the list (notepad), and post it here.
Let\'s take a look at what\'s running.
