I had installed Windows Xp on my system. The problem is that whenever i try to turn on my pc and try to work on it, it gives out an error message stating that " you may be a victim of software counterfeiting crack" on my desktop screen. It doesn't allow me to work further and gets freeze up in between. Then i have to reboot my system, but after rebooting my system it shows me the same error message on my desktop screen. Can any body tell me that why i'm having such problem on my pc? Does any body knows about it? kindly help me out to resolve the above issue.
