To be honest with you I am really getting on a downer about the lot of them... I bought zonealarm security suite pro because I have never had a problem with the free version and since then I have regretted it - the pro version seems to just do things itself and regularly locks me out of things just for a laugh.
I've tried a couple of others and they have all disappointed. Even kaspersky which I used to love fails on my laptop so I can't use that.

At least zonealarm doesn't mess with internet explorer or firefox like Norton does... Or at least it hasn't messed with them on my computer yet...
