Another tuth is that some hackers can embed the .dat extensions to various virii and trojan. Kazaa not being safe is an understatement, the true levity of the whole p2p idea is that it is not governed by a central sever and at times users forget this.

You should have enough security then> Also remember that YOU MUST SCAN AFTER EVERY DOWNLOAD! That will keep you safe to some degree.
