Hi,
- What is the Antivirus program installed on your computer?
- Are you aware of any changes made on the computer prior to this issue?
If you installed WebRoot Antivirus on your computer, I would suggest you to contact WebRoot Antivirus support for further assistance.

I would suggest you to use Microsoft Security Essentials to guard against viruses, spyware, and other evil software. It provides real-time protection for your home or small business PCs.
Microsoft Security Essentials is free* and we designed it to be simple to install and easy to use. It runs quietly and efficiently in the background so you don't have to worry about interruptions or making updates.
