Hay, I guess I have got a virus who is using bitlocker to encrypt and use a part of my hard drive. All the ordinary antivirus softwares were useless. Any solutions ?K.Aria

Hi, From this issue, I would like to suggest that you contact anti-virus software support to see if they have special update or tools to complete remove these viruses. You can also contact your antivirus vendor for assistance with identifying or removing virus or worm infections. If you need more help with virus-related issues, contact Microsoft Product Support Services. For information about Security updates, visit the Microsoft Virus Solution and Security Center for resources and tools to keep your PC safe and healthy. If you are having issues with installing the update itself, visit Support for Microsoft Update for resources and tools to keep your PC updated with the latest updates. I hope this helps. Thank you for your time and cooperation! Alex Zhao TechNet Community Support
