Hi,
I have a PC with an Antivirus virus file updated Automatically all the time. This PC is connected to two different networks A and B through 2 Network cards. The network A is fully secured and each PC on network A has an antivirus with automatic upgrade, but on the network B none of the PC are protected because they can’t be contaminated (can’t access Internet and have no USB, Floppy or CD drive). Can a virus that can only come from the protected network A can contaminate the network B without contaminating network A? In the other hand I understand that if Network A is contaminated B will be too.
Thanks.
