[citation][nom]zingam[/nom]It is ridiculous to pay hundreds of dollars for an OS and then to pay even more hundreds of dollars for AV and Firewall software. And then you are still not sure what might hit you from behind![/citation]
First of all, you can get both of those for free. Avast!, and Free AVG are both great and free.
Second, the article doesn't even mention what OS the FBI is using.
Third, There are much better methods to keep viri from infecting computers from the internet, and I'm sure the FBI uses such a system. I'm guess it was an idiot with a flash drive, doing something they shouldn't have.
