Can a virus be transfered over a wireless network from one computer to another?
Question: My 6 year old HP computer was recently infected with a virus. It seems to be beyond repair, it won't boot up in normal mode OR in safe mode, and the system recovery which resets everything to default, didn't help. This computer which is infected is the main computer on my home network. We have 4 computers (including the one i'm typing from now) on the same network. Whatever it was that was downloaded was downladed directly onto the computer which has died. I guess my fear is the virus will somehow spread from one computer to another without me knowing or doing anything actively to download it. Is this something I have to worry about, or is what I'm describing impossible?

It is possible, but it depends on the virus. If file and print sharing is enabled, its possible that the virus could find a file share on the network and infect an exposed file. Not all viruses do this, however. And if you do not have any available shares on a PC, there's nothing it can write to.
There are rare viruses that will attack and hide in your routers, but I doubt this is the case. Try rebooting any modems/ routers you have. Make sure all the other computers in the house are off and see if your notebook still does it. Then turn on one computer at a time until it starts acting up. You may also have a neighbor camping on your wireless if it's unsecured and that neighbor may have a virus. If you haven't done so yet, set up WPA and use a passphrase to secure it. If your first computer acts up even with only the router and the computer running, then you may need to either get a second program to scan for viruses (malwarebytes or "Spybot Search and Destroy") and run them. If you find no viruses, then you may in fact have one of those router viruses. If rebooting the router doesn't fix it, you will probably need to go to the web site of your manufacturer/ service provider,download the firmware and follow the instructions EXACTLY to re-flash the router. If you don't follow the instructions exactly you could turn your router/modem into a boat anchor.
particular it may only by using fact it fairly is instantaneous does not make it impervious to virus's or infections, greater the alternative. Ethernet is greater look after and swifter than instantaneous. instantaneous has obstacles to penetrate like partitions etc. advise you acquire malwarebytes>deploy>replace definitions>run rapid test, save on with up with finished test and AV scans. an entire scamn of malwarebytes takes 30 -40 5 minutes, pending on components, My laptop has 4Gb or memory and a three.06 Mhz CPU and takes 30 mnutes for a one hundred sixty GB force. Your instantaneous could be encrypted and password secure to steer away from undesirable purchasers? The othe rapid thank you to flow infections from one laptop to a various is thru means of a thumb force. A test in the previous it leaves a computer and because it fairly is inserted into yet another takes little or no time, thinking what may be the end result?
its possible that your computers cannot see each other because they are on different workgroups. right click on "my computer" (either in the start menu or on the desktop... whichever is faster) and choose "properties" from the list that pops up. click on the 2nd tab - "computer name" (this assumes you're using windows 2000 or xp... vista may be different I'm not on my vista machine now...) your workgroup should display here... it must be the same on all your computers to easily share printers and files... you can share with different workgroups but the printer won't show up transparently through windows. If your workgroups are different, select the "change" or "edit" button...(maybe rename?... my computer isn't in english...) and change the workgroup of the computer... click ok and then logout to apply the changes (you shouldn't have to restart... a logout/login should do the trick I think. If that doesn't solve your problem... then provide more details about your setup and hopefully someone will come along and have a better answer.
it could happen but if you gone on for a wile and nothing bad happend so far then i dont think it will happen, if your really worried about it then take the computer and get rid of all the programing (all of whatever OS your using) and put whatever OS your using back on the computer.
In this case, WEP (or any other encryption) is meaningless. That's a password to log into the LAN, and has nothing to do with virus containment or transmission. Once on a LAN, any 'network aware' malware can migrate over the LAN to infect other, improperly defended units. Conficker (still around & still a nasty character) is one example of this trait. Clean that infected unit before joining the LAN. It helps if all units on the LAN have firewalls installed, and all Microsoft updates; but there is no guarantee. ADDED: From "Security Now"; #231 (just this Thursday): "... So those ports, even though they are open and this SMB protocol flaw is there, you can't get it from the outside. The problem is that you can get it within a LAN. That is to say, so one of the things that we're seeing is, we're seeing trojans which we know like to spread within a Local Area Network once some employee brings an infected laptop into work and plugs it into his hub at his desk. If there's something bad there, it'll just go like wildfire. We've seen trojans that use open window shares to jump from machine to machine. Unfortunately the Server Message Block protocol flaw is available and exposed within a LAN." http://www.grc.com/securitynow.htm I do wish people would stop rendering bad advice on this site. Also note that WEP is next to useless as an encryption method. Apprentice level #1 to hack. Move that LAN to WPA or WPA2 with AES for maximum protection.
