Q. How do I keep my computer secure?

To keep your computer secure it is very important to make sure that you have the latest Windows Critical Updates installed on your machine.
If you are running the Windows Operating System you can download these updates at WindowsUpdate.Microsoft.com
It is also very important to make sure that your computer is running anti-virus software with current virus definitions (Updates).
Running a spyware removal software package (with current definitions) periodically is also advisable, usually at least once a month.
In addition to running real time AV software, it's also good to do a double blind scan from time to time using a different scanner. If you go to Housecall.TrendMicro.com, they have a good web based scanner.

Q. I think I have a virus! What should I do?

Most viruses are spread through email attachments. That is why you should never open attachments from a source you don't trust, also be wary of the type of attachment and the formatting of the e-mail - sometimes the e-mail maybe sent with a forged address that looks like someone you would trust.
If you believe that you do have a virus, you should update and run AV software (or install some if you don't have any).
Also try running HouseCall.TrendMicro.com to check for viruses your AV software may have missed.
You should also check to make sure that you are running the latest security patches for your Operating System and Software.
Nortan and McAfee both offer popular tools for detecting and removing virises. You can also find free online anti-virus scaners, like the one offered at http://housecall.trendmicro.com (however, this is not a substitute for realtime continuous scanning).
If you find and remove a virus from your computer, it's a good idea to do another scan until you don't find a virus.
If you have a specific virus but are having difficulty removing it, there are several sites with details about viruses, and possibly tools that will remove the virus you have. Symantec for example, has a virus tools section, and details on a lot of viruses.

Q. I think I have spyware! What do I do?

Spyware is generally spread through "malicious" websites and "freeware" programs. They usually track where you go and what you do on the internet, for marketing research and advertisement purposes.
You can detect and remove most spyware by running a spyware removal tool like Ad-Aware from LavaSoft.
You should be aware that some "free" software that you may use could require the spyware to be installed for it to work correctly.
You can also block some web browser based spyware by tightening your browsers security settings.

Q. Do I need a Firewall?

In general, a Firewall will protect your computer from outside attacks by "filtering" out what it believes to be harmful content from coming into your computer.
You can download firewall software to run on your computer. A few popular titles are BlackIce Defender and ZoneAlarm.
Many Routers/Switches come with simple port blocking firewall solutions that you can configure for added network security.
For personal use, most people will not need a firewall (already being behind a NAT device). For business use, it would be wise to look into.
If you do plan on using a firewall you should make sure that you configure it correctly. If you block the wrong port numbers, you could block yourself from sending email, connecting to ftp servers, or even browsing the internet.
