DOES A SECURED WIRELESS NETWORK PROTECT OTHER COMPUTERS ON THE SAME NETWORK FROM VIRUSES? IM USING A LAPTOP AND I DONT WANT VIRUSES THAT I PICK UP ON MY LAPTOP TO CONTAMINATE THE REST OF THE OFFICE. Hypothetically if i picked up a virus could it travel over my wireless signal go into my linksys cisco router and infilirate the other computers? WOULD CHANGING THE UNSECURED WIRELESS NETWORK TO SECURED WEP OR WPA(2) be a preventable measure to help this or not? sorry for the random caps dont take this as me yelling!
