Need computer help
by PooBear1227 - 12/28/08 3:00 PMI need to know if someone in the house goes to a site that can be potetnially unsafe, can the other computers that are networked get infected? We are connected via a wireless adapter on the 2nd computer. Another computer will be hooked up the same way in the next month.
Please let me know as soon as possible.

no

There are a number of things to protect your computer on a network.. First, make sure to use a separate firewall on your computer as well as on the router you're using. Next, if you don't want to share your files and printer with others on the network, disable "File and Printer Sharing for Microsoft Networks" in the Control Panel/Network Connection section. Be sure that you have all Windows Updates installed as well as updated antivirus and antispyware software.. Next, be sure that ALL users on your computers have a complex password..and that includes the hidden administrator account on Windows XP HOME..
As to your concern about another computer visiting "bad" sites, if the network belongs to you, it's up to you how you want to enforce such.. Check your router as to it's logging abilities.. If the second computer is yours as well, created a special limited user account, with a password, for those that you are concerned with.. It is possible to limit the sites that are visited.
Hope this helps.

There are a number of network aware viruses and worms that CAN infect networked computers. Some occur when visiting infected sites and some occur because someone inappropriately opened an attachment from removable media or to email. In such cases, the viruses hunts for vulnerable computers on the network and can infect them without the user doing anything.. Although most of the newer trojans which are activated by visiting websites are not such worms, there have been a number such as those listed below:
Klez
W32/Bugbear
W32/Mydoom
Blaster/Lovesan
Notepad.exe/QAZ Trojan
As a system admin for a government agency, I've had to clean out a few..
Hope this helps.

Just Because You Weren't Infected On ONE Network...

...doesn't mean there aren't network aware worms that can infect others. Not all malware is network aware but some types are. Certainly, they aren't as popular as they once were but such malware is still out there. It's a good idea to know such things are in-the-wild and to harden your system against them. Do the research... (Think about the older Magistr and SirCam worms.)
I've helped cure the problem for a number of networks, one with thousands of computers and multiple domains, and a couple smaller home networks as well.. You'll be sitting at the computer doing nothing and BAM, your antivirus shows you've received an infection that came from the network.. About eight or nine years ago, we had a tough time removing the older "W32/Funlove" worm from our agency network but eventually, a fix was released and we patched our system..
Hope this helps.
