Hi,
I dont know if this the right place to post this question here,but I need help getting
windows defender to work. I get a message saying evertime I try to start it, saying
that the application failed to initialize 0x800106ba. a problem caused this program's service to stop.to start the service, restart your computer or search help and support
for how to start a service manually.Some start up programs are so annoying and would appreciate any advice .
thankyou,
