I wanted to know if a virus can actually reside in a cable modem and infect a PC. I work in a law office and we keep a few computers off the network for security issues. The situation is I just reformatted a PC, re-installed the OS (Windows XP) and I am about to hook it to the internet to download all the needed updates. Like most small offices we have a cable modem connected to a wifi router that most people in the office use for tablets, cell phones, etc. All these things are personal items and have the ability of contracting virus because of all the internet browsing they do at home, coffee shops, etc. What I figured I would do is disconnect the modem from the router and then hook it directly to the PC then download the updates. I planned on rebooting the modem so nothing is stuck in its memory, but I just wanted to know if I went ahead with the plan above is there any risks of a virus being passed onto the PC that I am updating?

P.S. I have the standard Motorola "Surfboard" cable modem SB5101U

Connecting the computer directly to the internet with out a firewall or Using NAT is not any better then what could be lurking on your network. If the computers are not connected to the internet for security reasons dont connect them. You can use WSUS Offline updater to download all the Microsoft Updates you may need. You can also download most Antivirus and security software updates manually from the manufactures website. If You installed Windows XP without service pack 3 Microsoft updates may not run correcty untill you update to SP3.  REMEMBER After April 8, 2014 Microsoft stops Extended support for XP.

:thumbup2: Thanks Queen Evie! They beat me to it. If the computers you restored are using A Raid setup you should use a secure erase utility such as Dban to Secure Erase the HDD before reusing them. Left over Metadata from a Deleted partition without proper reformatting can lead to more problems in the very near future.
