Since installing the 2004 Norton internet security each time the computer is started I receive the security notice " KHOST.EXE is attempting to access the internet" The recommended action is to 'block' this,but even by doing so (ticking -always use this action),the warning reappears for a few times consecutively. What precisely is KHOST.EXE please ?
I also frequently receive "Msimn error" since installing the security software. What does this pertain to please ?
