Always get paired up with a good firewall first. The free version of
zonealarm will offer all the containment you'll need for outgoing and incoming connections. Great for keeping **** from getting in and great for keeping **** in....that's when you get an anti virus program. Avg antivirus is free and is a good one many users turn to, but the best in my opinion for free antivirus is
Avast4home made by alwil software.
Anyway, if for some reason a virus did get into your computer from something you downloaded and executed,
zonealarm will usually tell you the name of the program trying to access the net which is probably going to be that virus. From there you can click deny to not allow the virus access to the net keeping your virus infection contained. Containment is so nice, keeps viruses from getting to other computers, after containment use your good antivirus program to be rid of the problem once and for all.
This is all i do, and yes i've had a virus or two, but this is how much easier being beefed up with a good firewall and good antivirus will be to get rid of infections. And if someone is using dialup, never tell them they don't need an antivirus or firewall because of their low bandwidth, viruses are pretty tiny and they don't take that long to get onto a computer using dialup.
Just for reminder the **** i recommend and use.
Zonealarm - download the free version and only install the basic firewall instead of the 15 day trial with all the bells and whistles(so many people get tripped up and install the trial instead...just keep your eyes open it's not hard).

avast is for linux as well...want a good firewall for linux, try the iptables frontends
guarddog(this ones better) or
firestarter). I can't even begin to praise how ****ing good avast is, i'd definitely pipe down the money for it if i needed antivirus for non-home use(avast for home use is free).
http://www.avast.com/eng/download-avast-home.htmlUse good software like this and you should be more than well off and good, happy, alive and kicking, more wise, etc...unless you guys like to pay for you firewall and antivirus(why when you don't have too). Mcafee and norton are the worst antiviruses and firewalls ever, plz don't use them, avast and zonealarm is so much better. Pretty much i emphasize do what i do and you'll stay away from the bull****.
