I would suggest you to try the following steps:
Refer the Azeez N replied on May 12, 2011 on Microsoft forums.
Note: Refer "How to reset the computer to start normally after clean boot troubleshooting" to reset the computer to start as normal after troubleshooting.
Important Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you shouldn't disable your antivirus software. If you have to temporarily disable it to install other software, you should re-enable it as soon as you're done. If you're connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to attacks.
Hope this information is helpful. Please do let us know if you need further assistance, we’ll be glad to assist you.
