Hi.I'm coming again to this forum because i'm sure that you will help me again to resolve several windows problems.
This time the issue is the Microsoft security essentials.When i click it nothing happens.It was working properly and i didnt install a new security program.I try uninstall and reinstall with no luck.I try to run yours repair tool with: reset file permission,register system files,repair wmi and remove policies,but the problem didn't resolve.
