I'm just about to set up my laptop to access the internet wirelessly. I have cable broadband and have Norton installed on my main PC. Will I need to install an antivirus program and firewall on the laptop as well?
WPA & WEP are the the types of 'security codes' that stop just anyone using your wireless broadband connection. Assuming you have a wireless network at home, without this security anyone in range can use YOUR internet connection.
As to your other point, yes you will need antivirus and firewall on your laptop. Norton grinds everything to a halt. bobbybowls has recommended two of the most popular and effective free programs. The improve the security offerd by windows own firewall.
OK, thanks for that. Sorry to be a bit thick, but am I right in thinking that you should only have one firewall running, or can you have more than one - would I need to disable the Windows firewall before running a different one?
Zonealarm will run over the top of windows firewall and protects you from 'malware' sending stuff out from your PC as well as blocking stuff coming in. Windows firewall is basic and only blocks inbound stuff.
i use zone alarm on my laptop as i connect to lots of different networks, but for the desktop it is just windows firewall and the routers hardware firewall. look at this website for recommended software to protect your pc. click here
I'd definately recommend Zone Alarm for your firewall. I've been using their products since I first got online and have never had a problem except when connecting to a university network (which was obviously very well protected anyway).
You might want to install some anti-spyware software as well and check frequently - its a worthwhile precaution. I use AdAware, although the link in bobbybowls post suggests some others. useful stuff in that little link!
