Ten Commandments
1. Dont assume anything. Make some time to learn about securing your system.
2. Acquire and use a reliable antivirus program. Select an antivirus that has a consistent track record. Checkmark, AV-Test.org and TuV are among the most respected independent testers of antivirus software.
3. Acquire and use a reliable firewall solution. Again, independent reviewers are your best bet for reasonable choices. Some operating systems come with a firewall which only filters incoming traffic. Use a firewall that can control both incoming and outgoing Internet traffic.
4. Do not open e-mails coming from unknown or distrusted sources. Many viruses spread via e-mail messages so please ask for a confirmation from the sender if you are in any doubt.
5. Do not open the attachments of messages with a suspicious or unexpected subject. If you want to open them, first save them to your hard disk and scan them with an updated antivirus program.
6. Delete any chain e-mails or unwanted messages. Do not forward them or reply to their senders. This kind of messages is considered spam, because it is undesired and unsolicited and it overloads the Internet traffic.
7. Avoid installing services and applications which are not needed in day-by-day operations in a desktop role, such as file transfer and file sharing servers, remote desktop servers and the like. Such programs are potential hazards, and should not be installed if not absolutely necessary.
8. Update your system and applications as often as possible. Some operating systems and applications can be set to update automatically. Make full use of this facility. Failure to patch your system often enough may leave it vulnerable to threats for which fixes already exist.
9. Do not copy any file if you don't know or don't trust its source. Check the source (provenance) of files you download and make sure that an antivirus program has already verified the files at their source.
10. Make backups of important personal files (correspondence, documents, pictures and such) on a regular basis. Store these copies on removable media such as CD or DVD. Keep your archive in a different location than the one your computer is in.

Windows XP vs. Xandros Linux
The Verdict
When you look at the final scorecard, the Linux-powered Eee PC wins by a TKO, taking four rounds and fighting to a draw in the productivity round. The XP Eee PC wins three rounds outright: peripherals, multimedia, and adding applications.
Ultimately, deciding which Eee PC is best depends on your personal preferences. Windows XP may be the preferred choice by many users because of its familiarity, despite the fact that you have to do a fair amount of scrolling in some applications. It's also the better choice if you want the ability to install popular programs, and if you don't want to worry about which peripherals will work.
If you’re looking for a faster computing experience, longer battery life, and don’t intend on adding much software, the Linux-based version of the Eee PC should be right up your alley. The Linux Eee PC's tabbed-based interface won't be all that familiar to Windows users, but it's arguably the more user-friendly solution for a 7-inch screen.
Winner: Xandros Linux Eee PC
