I am running 2 computers, a laptop and a desktop, connected to the web behind a wireless router (the desktop is wired, the laptop wireless). I know routers provide good security. In the past I have run several firewall programs on the desktop before I got my router and I had so many problems with different programs getting hassle free access to the internet. Some were difficult to configure, others impossible to configure so I ditched the software and got the router. Although I have not had any problems, Im about to pass on the desktop to someone who also has a router but Im a little concerned about the way they use the internet, particularly email as they are not very safety savvy. Do I need to install some software or are they ok? I do have a very stable and secure anti virus which does more than enough for me so I have installed the same on the desktop to help with bugs transfered via email. Cheers.
