This morning I logged on my computer and it gave me this message on the lower right of my screen "you may be a victim of software counterfeiting. This copy of windows did not pass genuine windows validation" I've had this computer for about 4 1/2 years and it surprised me since its never done this, please someone help? Why is it doing this, the operating system has never been re-installed or messed with.
