I’ve had my 5 year old desktop secured with antivirus,spyware,firewall,adware,etc. I just purchased my first laptop & since I’m now wireless, my paranoia has come up. Aside from the usual antivirus/spyware/firewall protection, do I need to get something with “wifi security”, “bi-directional firewall”, and bluetooth protection(‘bluesnarfing’ and ‘bluejacking’ can allow attackers using easily available software to hack into data held on the laptops, or use the machine as a conduit for other activities)? With all these different security programs I’m starting to wonder if they’re really necessary. I’m running vista ultimate & IE7 (which have protection & encryption), Norton Internet Security, keep my file sharing “off”, & I’ll be installing Windows defender and Yahoo’s antispyware. Is this enough to keep my laptop data safe in a public wifi area or do I also have to get more security like the one’s I mentioned above? My apologies for the long post & gratitude to those who took the time.
