Why do people continually use things that take over their computer and strip things?
isnt that what we dont want as webmasters? restrictions and borders to hold us back?!?!
their are much simpler (and free things) out there to use
check zonealarm.com for a great firewall
http://www.grisoft.com has avg antivirus whichs is also free and pretty good to use
try the other things that are out there before jumping to something that costs money and screws you in the end
hope this helps,
