Unable to remove securityrisk.urlredir- getting scan status as ''partially resolved"

Hi

 

Can somebody help me remove securityrisk.urlredir? I have tried many of the methods listed here and on microsoft website, including Norton Eraser, but I think my pc is still infected....

 

In some solutions it is suggested to turn-off system restore- but I am not able to turn off mine- it gives the error message that "System restore encountered an error trying to enable/disable one or more drives. Please restart your machine and try again".

 

Also, my security center is showing error message "The Security Center is currently unavailable because "Security Centre" service has not started or was stopped." I am repeatedly getting the same error.

 

Thanks
