Antivirus programs protect you against malicious programs that run on your computer (via e-mail attachments, instant message networks, P2P, etc.). They look at your local files as you access them for suspicious contents.\n\nA firewall protects your machine against network-based attacks by blocking traffic according to rules, either by default or ones you set. (Some firewalls can also set privileges for applications, so only the applications you specify can access the Internet. If you get a malicious program, it gets blocked by the firewall.) It looks at your network traffic for suspicious activity.\n\nAnti-spyware programs either sit in memory and watch for identified sites or programs, or they "inoculate" your system against potential exploits, or they scan your machine for spyware on demand. They're like an extenstion of your antivirus protection. I use Ad-Aware, Spybot S&D, and JavaCool SpywareBlaster. They're donationware (Ad-Aware has a paid version you can buy, which gives you real-time protection).\n\nYou should really have at least antivirus and a firewall. If you have a router between you and the Internet, you can get away without the firewall, but it's still better to have one. This is "defense in depth" (or "belt and suspenders" for the engineer types) -- it's another layer an attacker has to deal with.\n\nI used to be a real advocate of Symantec products, but I've had  horrible problems with their recent versions and their activation scheme. I did some testing, and as a result, I went with Trend Micro's PC-Cillin, which includes antivirus and a firewall for your computer. The whole package is $60, I think. You can download a fully-functional 30-day evaluation copy at their site.\n\nDisclaimer: Other people I know have gone with Avast or AVG and been just as happy.

Look in your Firewall settings

Assuming it is a static IP (always on type of connection), it would be possible to attack a computer or network of computers.  This of course assumes malicious intent.  However, having a firewall in place provides protection from such attacks.

firewalls limit incoming and outgoing data either personal or group. they are designed to protect from malicious intentions.

yes.  it beats the pants off of microsoft's default firewall and the norton and mcafee firewalls are resource hogs.

Hi, I'm a professional security consultant.  When it comes to firewalls there's no one "best" solution, there are only better choices depending upon what you need to protect and your budget.  For most home users with a computer that doesn't hold extremely sensitive personal information, the firewall built in to Windows is sufficient.  It's not a great firewall, but it's relatively easy to use and it's free with Windows.  If your computer has sensitive personal data on it (bank account information, family records, etc.) then I'd suggest an external firewall, such as one of the little boxes that Netgear makes that you can buy in the store.  These devices do a reasonably good job of keeping malicious activity away from your computer.  Personally, I don't like nor do I recommend software-based firewalls such as Zone Alarm or Norton.  While these software packages can do a good job protecting you if they're configured correctly, using a software firewall is kind of like putting a lock on the refrigerator to keep a burglar from eating all your food.  You're still letting the burglar into the house, just not allowing him into the refrigerator.  A hardware-based firewall is like putting a lock on the fence around your house -- a much better proposition!  Always go for the external firewall/router box if you can afford it.

Zone alarm is a good firewall, they have a basic free version which blocks as much as the professional version but doesn't provide support.\n\nAVG Antivirus is a good free antivirus software.

Thinkgeek.com has something called the Stingray Firewall - it's a hardware firewall that learns what to block in a very intelligent manner. It will not get in the way of games, web browsing, or other normal internet activity; it will stop all intruders like a brick wall that's been set on fire. Setup is ridiculously easy, just plug in all the right stuff and you're good to go.
