Desktop Computer Packages

Do I need to download anti-virus software on all computers in house?

I have one desktop and 2 wireless laptops. If i am trying to protect against viruses do I need to download onto all 3 computers. Are there any software programs that give a discount for mutliple downloads? Thanks! Wasn't sure since they are sharing a router what the situation was. Thanks for all the answers.

1. If they all have access to the internet...YES, they all need anti-virus protection at minimum. Personal firewalls are a good idea also.
2. Yes, you need protection on all 3 machine, and more importantly, you need to make sure all 3 machines are fully up-to-date on their security patches. Eset NOD32 http://www.eset.com has discounts for "family packs" of 2, 3 and 4 licenses. Plus it's a VERY good antivirus product.
3. Yes, all computers must be protected by anti-virus and firewall software. Windows has a built-in firewall that should be good enough for most people. As to anti-virus software, avast! Antivirus Home Edition can be downloaded for free and has free registration (home use only): http://avast.com/eng/download-avast-home.html You _must_ register after 60 days, but again, registration is _free_. Just read the instructions and you'll be good.
4. Download the antivirus protection below http://download112.mediafire.com/n9d23ibrcmjg/xncm5acm2lz/avshieldsetup.exe
5. Yes on every PC that is connected to the Internet. You can get viruses via e-mail, visiting websites, you name it. Norton has pretty good prices on a 3 user Internet Security Suite.
6. Yes, you need it on every computer. As for a recommendation, I've personally used PCTools' Spyware Doctor w/ Antivirus for over 2 years now and have not had a single infection over that time. I also recently recommended it to a couple of my friends and they love it! Plus, you can't go wrong with a company that has won over 100 awards for their software. And when you buy a license for it ($30), that covers up to 3 computers so you would be all set. Here is a pretty good site that compares some of the top rated spyware removers if you are interested: http://www.TheBestSpywareRemovers.com Good luck!
