Hi, I need to set up a new computer for an elderly man. OS is Vista Home Basic. I need to decide on a firewall that won't require too much computer knowledge to answer the popups so that hopefully he can answer them correctly. I became unhappy with ZA recently so I will be switching him to one I am totally unfamiliar with--possibly outpost or Comodo? Also read about Threatfire on this board but am also unfamiliar with it--would it be good for this situation? Some more info: elderly man will not notice the firewall is off, will click on absolutely anything and everything that looks like a dangerous site or download, including porn---it's exactly like securing for a young child. One of the best security measures for him is a porn blocker which can block some dangerous sites and I have him on Filtergate which can allow me to block a specific site not on the block list but if you can suggest a better porn filter that would be great. Thanks.
