Answer
You still need a full range of security software on eextremely
computer on the network when using wireless from a hub. with bought security you would need a seperate cpoy for each machine. i have used avg anti virus, zone alarm firewall, spy-bot search and destroy and ad aware both spyware killers for years. they are
all free for personal use and i have had no trouble with viruses trojans etc. avg does not slow the system down as much as some other products and zone alarm allows a lot of personal configuration unlike the windows firewall. they can all be downloaded from the following link. http://www.computeractive.co.uk/ on the home page select downloads and then the appropriate category.i also use windows defender from the microsoft site. it is safe to use two anti-spy products but never use more than one a/v as it can cause conflicts. you should run a/v and anti spy weekly. hope this helps.
