Social networking websites like MySpace, Facebook, Twitter, and Windows Live Spaces are services people can use to connect with others to share information like photos, videos, and personal messages. As the popularity of these social sites grows, so do the risks of using them. Hackers, spammers, virus writers, identity thieves, and other criminals follow the traffic.
Read these tips to help protect yourself when you use social networks.
1. Use caution when you click links that you receive in messages from your friends on your social website. Treat links in messages on these sites as you would links in email messages.
2. Know what you've posted about yourself. A common way that hackers break into financial or other accounts is by clicking the "Forgot your password?" link on the account login page. To break into your account, they search for the answers to your security questions, such as your birthday, home town, high school class, or mother's middle name. If the site allows, make up your own password questions, and don't draw them from material anyone could find with a quick search.
3. Don't trust that a message is really from who it says it's from. Hackers can break into accounts and send messages that look like they're from your friends, but aren't. If you suspect that a message is fraudulent, use an alternate method to contact your friend to find out. This includes invitations to join new social networks.
4. To avoid giving away email addresses of your friends, do not allow social networking services to scan your email address book. When you join a new social network, you might receive an offer to enter your email address and password to find out if your contacts are on the network. The site might use this information to send email messages to everyone in your contact list or even everyone you've ever sent an email message to with that email address. Social networking sites should explain that they're going to do this, but some do not.
5. Type the address of your social networking site directly into your browser or use your personal bookmarks. If you click a link to your site through email or another website, you might be entering your account name and password into a fake site where your personal information could be stolen.
6. Be selective about who you accept as a friend on a social network. Identity thieves might create fake profiles in order to get information from you.
7. Choose your social network carefully. Evaluate the site that you plan to use and make sure you understand the privacy policy. Find out if the site monitors content that people post. You will be providing personal information to this website, so use the same criteria that you would to select a site where you enter your credit card.
8. Assume that everything you put on a social networking site is permanent. Even if you can delete your account, anyone on the Internet can easily print photos or text or save images and videos to a computer.
9. Be careful about installing extras on your site. Many social networking sites allow you to download third-party applications that let you do more with your personal page. Criminals sometimes use these applications to steal your personal information. To download and use third-party applications safely, take the same safety precautions that you take with any other program or file you download from the web.
10. Think twice before you use social networking sites at work.
11. Talk to your kids about social networking.

5 Common Computer Security Mistakes
Computer security mistakes can be a painful and costly experience. The good news is that with a bit of thought, planning and vigilance you can effectively protect yourself. Here are 5 common computer security mistakes to avoid.
No Antivirus/antispyware software.
The key facet of this element of computer protection is keeping your software and virus definitions up to date. Most worthwhile anti-malware programs (the term “malware” includes viruses, spyware, Trojan horses, keystroke loggers and other forms of malicious software) make it easy to check the date of your last update and to easily launch the update process manually.
Since most anti-malware/antivirus software is sold on an annual basis you need to purchase a new license each year. If you let your license lapse you will be unprotected against any new malware. So even if you have an active antivirus program, but it expired six months ago, you will not be protect from any new viruses or malware that were released in the last six months since it expired. A definite security mistake.
No Firewall software.
Some people feel that having an antivirus program is all they need. A definite computer security mistake. Firewall software acts as a filter to protect your computer from malware and intruders. If some form of malware does get on your computer, firewall software can prevent malicious programs from connecting to the Internet.
Like antivirus software, the firewall software must be updated regularly. This is all the more reason to use an Internet security suite which ties these two important elements together for updating and renewing. At the very least, make sure that the built in Windows Firewall is enabled.
Not keeping Microsoft Windows, Office and Internet Explorer up to date through the Microsoft Updates process.
Microsoft produces software updates, patches and bug fixes for its products on a regular basis. Updates are free and can be manually downloaded or Windows can be set to automatically download and install them. Periodically Microsoft combines a group of these “updates,” adds some additional functionality and features, and delivers them in what is known as a Service Pack (SP). We strongly recommend that you install all service packs as they become available.
It is strongly recommended that you keep current with the latest version of Microsoft’s Internet Explorer web browser which is now up to version 9.0. At the very least no one should still be using Internet Explorer 6.0 as it presents serious security compromises to a computer. If you use the Mozilla Firefox browser, which is an excellent alternative to Internet Explorer, be sure to keep up with the latest updates and version through Firefox Updates.
No Email Spam Filter.
As most users are aware email spam is a huge culprit in the spreading of malicious software. Have a good spam blocking program and have it set to a high enough level. Some email packages such as Outlook, Yahoo mail and Gmail have built in spam blocking/capturing functionality. If your email program does not provide effective spam blocking there are a number of effective and relatively inexpensive spam blocking programs available from third party software publishers.
It is important to remember that spam filters are not 100% effective and some junk will get through. It is best to follow some email self-protection rules of thumb including:
1. Do not open email or email attachments unless you know who they are from.
2. Never download an attached file from an email that you weren’t expecting to receive.
3. Never click on “Unsubscribe” on an email that you suspect to be spam or junk mail. This will just tell spammers that your email address is active and you will likely end up getting more junk mail.
4. Never click on an email attachment with an .exe file extension such as “myfile.exe”. These are program files and clicking on them will begin running a program that could be nasty.
5. Never click on a link within a suspected spam email – just delete the message immediately.
Not keeping your various security components up to date.
This was mentioned earlier in this post and regardless of the specific parts and pieces that make up your security solution you need to pay attention to them periodically to make sure everything is up to date and functioning correctly. While most security components are updated automatically it is highly recommended that you check occasionally to make sure that these updates are taking place and that your components are up to date. New viruses, spyware and other security threats are released almost daily. If your software expires or gets out of date, your system becomes susceptible to new threats.
There are a number of elements that play a role in keeping your computer secure. Making sure you have the five items above covered will provide a significant level of protection. As mentioned in #5, vigilance is a key. It is also important to take immediate action if you think you have been infected. Letting a potential malware infestation go for days or weeks will make the problem worse and provide an opportunity for additional forms of malware to be downloaded onto your computer. Awareness of your computer and Internet security programs and settings will play an important role in keeping your computer and your network secure.
