So for some reason this computer got a notification about its possible pirated etc etc and then so I used daz loader again and now it shows status Licensed but Microsoft Security Essentials wont pass validation ?
If you've ever used any other activation tool then that could be why. Also blocking the WAT update or adding entries to the hosts file may cause issues. You could try using WAT Fix if you're unsure though. Just be sure to follow it's instructions and tips perfectly. What would help a lot is to see an MGADiag report.
I managed to fix it, after I used your loader I opened MSE and clicked revalidate and at first it still said it had issues and then it fixed itself. So its good, Also I never used any loader or activator besides yours. Thank you DAZ
