In some parts of the world the pirated software market is usually large and many illegal copies are marketed and sold even before the original copy can be available. These pirated copies require and activation. This is a policy introduced to check pirated copies. But crackers seem to always have their way by finding ways to trick the system and crack the activation codes of the OS.

Only customers of Microsoft's volume licensing deals can presently download Windows Vista which will be generally available after January. The Trojan is likely to hit businesses who pass on copies of the Windows Vista operating system to friends or family.

The supposed Windows Vista crack is named Windows Vista All Versions Activation 21.11.06. This is doing the rounds of the internet and those who are tempted to get in illegal version of the recently released operating system and download the crack are in for trouble. When Windows XP was launched the hack was then launched by Devils0wn group to bypass the activation needed for Windows XP OS.

The high threat level Trojan is called "PSW.Win32.LdPinch.aze". Many do not expect this and apparently most antivirus scanners recognize it but NOD32 from Norton fails to recognize it.

Another major worry for businesses is that the new operating system is designed to make it easy for third party softwares to be integrated and used along with the operating system. This makes it easy for hacker as it is just the same as that of Microsoft partners to insert the code and pass it on.
