misconception
you need a firewall no matter what, if you value your data and privacy that is
Ok yeah for official matters may be....But i really dont care that much about data....I call my friends DATA hoarders(2TBs, 1.5TBs, Average 512+??GBs)....Hehehehehe.
And for me, Firewall does more harm than of use....I play online games a lot and its hard to configure and play it all at the same time....Ports...Hamachi...Garena...Gameranger...Steam....Xfire.....half of them stop working properly under firewalls.
And who needs so much of unwanted protection when i surf dirrty sites that are forum based and I have no lan access....AV takes care of pendrives.....And who wants a slower computer.
Peace~~~!
