However, I was referring to the security of the Network Router, in particular. I have learned that since it has it's own Firewall, with Security Passkey and WPA-2, that's pretty good security.

And, on the PC side of things, as you have mentioned, I also run Kaspersky (PC Firewall and Antivirus - Internet Suite). And in addition, an occasional check by Malwarebytes - AntiMalware (I'm sure you know it's freely available, although I have purchased a 'license' because I think it's so-good and only around $35AUD).

Don't get me wrong, I appreciate your help in this matter... it's that 'one' can get immediate answers through these forums!
