Just bought a new computer with windows 8 installed. Internet was fine until I installed ZA Internet Security 2013. Then it slowed down. Tried a bunch of fixes to other stuff, same result. I put ZA on snooze and internet went to normal speed. Turned it back on, and back to slow.

What can be done?

I am running Windows 8 on a brand new HP Envy. I have seen threads about Spybot interacting badly but I did not install that. It's clearly ZA as I can get internet back to normal by shutting it off.

I've been a ZA customer for about 8 years and don't want to stop now.
