Is my computer secure?

Question

Okay guys I have 3 computers hooked up to a WPA2 secured wireless router. All three computers have Kaspersky Internet Security 6.0 installed and I have Adaware and Spybot installed. I am not that concerned about my computer getting infected since I also have good browsing habits however I am a little worried about my brother who also uses the router. He dosent download anything or use any peer to peer programs but he does visit shady websites from time to time. Is my protection enough to block viruses and spyware from his computer from just viewing sites and never downloading? More importantly is my computer safe? Since I am using the same router what are the odds spyware or a virus can get on his computer and make it to my computer through the router with all the software I have installed?Please let me know if I am just paranoid or if I have to install additional software.
Also since I cannot babysit my bro please answer the question assuming he will visit shady sites...

Answer 1

If no one touches your computer but you then don't have tobe paranoid. He has his own computer then whatever he download or sites visited it not gonna affect your computer. Router is only sharing the Internet connections It doesn't transfer viruses, spyware, malware or what ever to your system. You have encryption on to logon and I assume you password protect the router too.

Answer 2

Stop tripping bro.
its highly likely he will get ad robots and crap on his computer if he goes to shaddy websites, but the likelyhood of it jumping to your computer is almost none if you have file and printer shairing turned off, and arent running files shaired on a network drive.
