It's pretty much that simple.
If I shut down Zonealarm I can't run anything.
It tells me I don't have access and the icons disappear on slews of shortcuts as if the files don't exist.
Oh and I can't upgrade Zonealarm either.
As it stands if Zonealarm breaks I'm not sure if my PC would ever be usable again.
Operating System:Windows XP Pro
