Hi Zenobia!
WOW! That was a L O N G time ago when that excellent operating system XP was in use!!!
So if now in Win10 if the 'lock hosts file bug' is long gone am I correct in thinking that the 'Box' in ZA that locks the hosts file can now be safely left 'Unchecked'?
Turning it on and off is a bit of an imposition to go through before and after running the SB Immunization scan, and thinking of computer users who might not be as competent in carrying this out, then if leaving it Unchecked will make it easier for them!
Cheers.
