ATI TV Wonder Pro and firewall concerns

by joehawk1 / October 29, 2004 11:36 AM PDT

I installed a ATI TV Wonder Pro card, and split my cable so I can be online and also watch TV without having to switch the coaxil cable each time I want to switch. I am running Windows XP, and use Sygate Firewall for online protection. I have now started to be concerned that there might be a way for someone to hack into the computer or introduce a virus etc, through the TV connection to the ATI TV Wonder Pro card, since it does not run through a firewall. Is there any need to be concerned?

Joe,

This may need correction for I am not well
vested in this area.

Your cable carries many frequencies. This allows the many TV stations you receive and Internet connection. The frequencies are seperated by the TV tuner and modem.

The modems job is to seperate the Internet frequency and convert it from anolog to digital (0 & 1's). The TV turners cannot do this.

As Computers can only understand digital input
an attack cannot happen thur the TV frequencies.

Thank you Bill for the reply. Your reasoning makes sense to me, so I won't worry about it. Thanks again for you help. Glenn

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
