Windows 7: Can i virus spread like this?

Can i virus spread like this?

Hi, recently my two sisters got computers and have a habit of going to random websites or clicking adverts/downloads.

my question is, if one of them got a virus or some kind of malware could it spread to my computer or others on the setup we have?

okay, none of the computers have file sharing or anything like that, although all are connected to the same router (they have wireless, im using wired)

Again none are networked exactly, but are connected to the same router, each has some form of firewall and anti virus.

any more information please ask, i will be around for 20 minutes, otherwise ill check here tomorrow.

thanks in advance

Never say never ! I had it happen once when I connected an infected computer to my wired network & made the infected computer a member of the workgroup

Took me a couple of days to clean up the mess

Better have them get MalwareBytes Free version, and run that along with good antivirus, etc.

yea good antivirus on all, malware bytes on most i think, will check and NO sort of network, file share or workgroup is setup, only internet, unless its set by default, but im sure it does not.

so it should be fine?

Are they all the same versions of Windows ?

You can check what workgroup Windows 7 computers are on by typing

Workgroup in the Start/search window

My niece's computer infected my sister's whole network regularly and I would get to come over to chase bugs around the house.

First put MS Security Essentials on each computer while disconnected from the network, run a Full scan. Next run Malwarebytes or another AV of your choice from bootable CD: FREE Bootable AntiVirus Rescue CDs Download List

I have done this over the years using AVG, then Avast and now MSE. So far, MSE is holding fast once the network is turned back on after disinfection.

Worms.

1) You can receive a worm via e-mail, in the form of an attachment. If you click on the attachment to open it, you’ll activate the worm, though in some cases, you don’t even have to click to activate it. Once activated, the worm will search for a list of e-mail addresses by going through files on your computer, such as your email address book and recently visited web pages.

It will then send emails to all the addresses it finds (say your sisters'), with a copy of the worm as an attachment. The process will then be repeated on the receiver's computer. Some worms even have a mail server coded into them, so your email program doesn’t even have to be open for the worm to spread.

2) There are other ways. There used to be the MyDoom worm, which copied infected files into Kazaa, thereby hitching a ride for itself.

Worms can do a variety of damage- open a backdoor into the infected computer, thus compromising it completely and even turn it into a zombie, steal information and launch denial of service attacks.
