Privacy Center is not Microsoft software. It’s a new form of fake antimalware software (also known as rogue security software) that pretends to help protect your computer, but is really a new form of spyware. It can slow down your computer and damage your files.
To remove the Privacy Center, download and use Microsoft Security Essentials, Microsoft Windows Defender, the Windows Live safety scanner, or another up-to-date scanning and removal tool.
For more technical information, see the Microsoft Malware Protection Center: Win32/Privacy Center.
