Buying a laptop is a major investment decision. As such it is not one that you should make lightly. Below are 5 tips that will help prepare you for making the best and most well informed decision when buying a laptop.

Tip #1 Size Matters

Buying a laptop is a matter that requires some thought. Consider the size and weight of the laptop. How often will you be carrying your laptop? Your answer will help determine which size and weight will best suit your needs. If you will be carrying your laptop frequently, a lighter model will be preferable.

The keyboard is another area to consider when buying a laptop. Why is the size of the keyboard important? A larger laptop will have a slightly larger keyboard area. But keep in mind that if you worry about your fingers or wrists taking on too much stress from typing on a keyboard that is too small, you may want this to be a main factor in your purchasing decision,

Tip #2 Choose Your Mouse

A laptop it will come with a built in touch pad, an alternative to the mouse, whereby the pad is controlled by the user’s finger movement. For some people, this type of pad is uncomfortable and not easy to work with. Before purchasing a laptop, determine what mouse options are available. Test each one and determine which one best meets your needs.

Tip #3 Wireless Options

Today, when many people think laptop, they think “wireless”. No doubt people want to make sure that their laptop computer will be able to access the Internet with a wireless connection. Many try to account for this by ensuring that their laptop has potential upgrade options, such as room for an expandable PC card or a USB port. However, since so many laptop users are looking for wireless connections, many of today’s laptops come pre-wired for wireless Internet. All you need to do is activate your wireless Internet service, and your laptop will take it from there. So depending on your needs, choose your laptop whether it is capable of expanding or if it is already configured for wireless Internet.

Tip #4 Check for Ports

Peripheral equipment will be connected to your laptop through USB ports. You will make your life much less complicated by ensuring that your laptop has adequate ports. Connecting equipment such as printers, scanners, and digital cameras will be much simpler if you have the ports readily available. If you are not sure, thoroughly read the specs for any laptop that you are considering purchasing.

Tip #5 Check Your Budget First

Finally, when buying a laptop, beware that you do not overspend. First create your budget and stick to it. When you think that you have found the laptop that you want, do not rush into it. Wait a day and check over your budget, requirements, and see if you are still as excited about the laptop in the morning, as you were when the sales clerk was showing off its specs. If you still feel that it is the laptop that you want to purchase, then go for it.

If you believe what you hear in the media, there are an awful lot of viruses going around. No, I’m not talking about the make-you-sick kind of virus, though they get plenty of airtime, too. I’m talking about the kind of virus that enters via your internet connection rather than your nasal passages.

What the mainstream media often don’t tell you–at least, in most radio and television newscasts and in the crucial headlines and opening paragraphs of newspaper articles– is that many of these “viruses” are not viruses at all.

What Computer Viruses Really Are

The main reason the mainstream media always are in alarm over viruses is that they tend to call any malicious computer program a virus. In reality, there are at least eleven distinct types of malicious software, or malware, commonly affecting computers today. The most common of these are worms, Trojans, and spyware.

So, what’s the difference between computer viruses and the other types of malware? The difference is that computer viruses are just about the only ones that regularly shut down computers and cause other obvious damage. The most common of the other kinds of malware–worms, Trojans, and spyware–are usually only detectable with a special scan.

The Real Danger of Computer Viruses

If the other types of malware are so unobtrusive that they can only be detected with a special scan, then what’s to worry about? For starters, these programs are called malicious for a reason: they are designed to cause some kind of damage, if not to your computer, then to someone else’s.

Worms are most famously used to damage, destroy, or disrupt other computer networks than the one on which the host computer is located. For instance, worms have been used by website owners to shut down rival websites by sending overwhelming numbers of requests to the computer that hosts that website. Worms have also been used to send out viruses to other computers, often without infecting the host machine–after all, what would it benefit the worm to shut down its host computer?

Trojans, in turn, are often used to insert worms and other malware on your computer, even if the Trojan itself does no damage.

But even if you don’t care what happens to anyone else, you should still be concerned about one kind of malware: spyware, a kind of malware that, true to its name, collects data from your computer and sends it back to a remote host.

Most spyware is only interested in monitoring your internet usage so it can tell other programs, called adware, what advertising to popup on your computer. However, there are criminal spyware programs that steal financial data, or perform a thorough identity theft. Don’t think you have personal or financial data on your computer? Some spyware programs contain a keylogger, which is a program that copies whatever you type, usually in order to snatch passwords. Even if you keep no financial information on your computer, if you ever buy anything over the web, the keylogger would allow its owner to buy stuff using the same information you typed in to buy stuff yourself.

Why Blame the Media?

Given the danger of all these different types of malware, isn’t it a good thing that the mass media are becoming hysterical about it? And can’t they be forgiven the sloppy reporting of calling Trojans, worms, spyware, and other malware “viruses”?

No, no, no.

This is a classic case of bad reporting doing more damage than no reporting at all. In this case, the damage bad reporting has done is to promote a common myth that goes something like this: “The only malicious software is a virus. Viruses damage your computer. Therefore, if my computer is working OK, my computer has no malicious software. I only need to scan my computer for problems when there is a sign of problems.”

Thanks to this myth, many people complacently let their antivirus software go months out of date, not wanting to be bothered with scheduling an automatic update. Just as bad, many people don’t have any extra software to combat the other types of malware that may not be covered by antivirus software.
