Hi! i have try to reverting the system but nothing is change, it say that
there's nothing different and give me an error! The antivirus say that's all
is ok!
no, i haven't installed any applications, i've only delete some documents
that was on desktop!
THANK YOU!

Go to Start > All Programs > Accessories and right-click
on the Command Prompt and choose "Run as administrator".
Type in: SFC /SCANNOW and press your Enter key.

If that does not work, try repairing your system. Boot from your Windows
Vista DVD, select the System Repair Option > on the setup screen, select
'Repair Computer > Select your installation of Windows > select Startup
Repair option and follow instructions.
