After Microsoft Security Essentials (MSE) is installed and seems to be runnning correctly, the MSE icon turns from green to orange, and you receive a message that states that the computer is not protected.


This issue may occur for the following reasons:
  • You use CCleaner from Piriform Ltd on the computer, and it has been used to clear the MSE history.
  • The date and time are not set correctly on the computer.
  • Other security software, such as antivirus, antispyware or anti-malware programs, are either fully or partially installed on the computer.


Warning This workaround may make a computer or a network more vulnerable to attack by malicious users or by malicious software such as viruses. We do not recommend this workaround but are providing this information so that you can implement this workaround at your own discretion. Use this workaround at your own risk.
