The size of computers today is amazing. I remember when I bought my first machine several years back, the hard drive was a measly 80 Megabytes. Today they are astronomical compared to those old dinosaurs. The speed, size, and computing power just seems to get better year after year. One shudders when one thinks of how they’ll be in ten years or so.

And if you take a look at some of the external hard drives that are out there today, you’d be amazed how big they’ve become. It was only a few years ago that they first started selling these. Now they come in all shapes and sizes. If you decide to wander down to your local electronics shop and pick one of these up, you might be in for a surprise. They aren’t so simple.

It’s important to know exactly what you want, and exactly what you want it to do before you go shopping. That way you won’t end up buying something that’s way too much for what you need, or on the other hand, you won’t end up buying something that just doesn’t have enough juice. When you figure out exactly what you need, you won’t be stuck with these common problems.

Naturally, the actual size of the hard drive you need to back up will be of considerable importance. If you are like most average computer users, and have a couple hundred GB sized internal hard drive, then 500 GB or even one TB will be enough for you. However, if you’ve got several machines with much larger sized hard drives, then you’re going to need some more horsepower to solve your back up needs.

The kind of media you will be backing up has an impact on the kind of drive you should buy. If you are going to be backing up documents and what not, then a smaller drive may suit your needs. If, however, you have plenty of music, and videos and other large sized files, then you will definitely need a bigger drive.

Another consideration is how often you plan on backing up your system. Some back up once a month, and that’s fine. Others back up every day, either before shutting their computer down, or as soon as they fire it up. This is another important consideration.

If you plan on carrying your external drive around with you, that’s another thing to keep in mind. If you only plan on setting it behind your computer at home or at work, you can probably get away with saving a few dollars. If, however, you’re going to need to carry it around, likely in it’s own case, then you may have to shell out a few more dollars. Keep these in mind when making a purchasing decision.

With these ideas in mind, you will be much better equipped to choose an appropriate back up system for your machine. Once you are set up and backed up, you won’t have any more fear of data loss if your system happens to crash. Happy shopping.

If you log on to the Internet, you certainly need anti-virus software. It does not matter whether you do not use a computer. Whatever you use to get on line you must have anti-virus software. Although there are hundreds of malicious idiots writing viruses to harass those who log on to the Internet from a computer, there is an growing number who are focusing on mobile phone users too.

It is more difficult to clear viruses from your cell phone as well, because there are less vendors for the anti-virus software and cell phone users are often less technologically knowledgeable than computer users, although the technique of clearing the virus is fairly analogous.

Let’s just use the example of using computers to go on line. If you go on line, your ant-virus software is your most essential item of software. It does not matter what you use the Internet for – transferring data back to base or receiving emails from friends – you are subject to attack.

For instance, if you use the Internet only to communicate with your head office, a hacker could try to piggy-back your link to gain access to the mainframe at head office and possibly access financial or other personal data and if you just send to and receive emails from your friends and family, you are open to attack from malicious fools around the globe.

If you use webmail such as that provided by Yahoo, Hotmail and MSN to name only the most popular, you will be protected from the most obvious attacks, but still not safe. If you obtain your email via an email client such as Outlook or Outlook Express, then you do not even have that small amount of security.

If you do not use email, but only surf the Internet for research or whatever, you are still not safe, because some websites and loaded with viruses, trojans and worms, waiting to unload them onto unwary surfers.

Therefore, whatever reason you surf the Internet for, you could do with some type of protection. Fortunately, anti-virus software for personal use is inexpensive and may even be free. Business users will normally get tax relief on their purchases.

However, be cautious with the free anti-virus software, because not all of it is effectual enough. The exceptions that spring readily to mind are Avira and AVG. These are exceptional products and have justly gained worldwide praise. Just Google the two names to get the download URL.

The anti-virus software that costs something (typically $25-$50 per annum) invariably offer one to two months free trial before you buy and a reduction in price, if you pay for more than one year at a time. Names that fall into this class are Kaspersky, McAfee, Norton and Nod.

Once you have selected your software, the following steps are the same for free and paid software. First install it and then configure it. If you are not certain how to do that do not worry, the default settings are fine for the vast majority of users. The only choice you will get that it is vital you make correctly is to allow automatic updates.

New viruses are being exposed or fixed every day and for your anti-virus software to be effective, you must permit it to bring itself up to date whenever it wishes to.

You know its bad news when you boot your computer and you get nothing but error warnings. Without the latest antivirus security software, your files and your system may be at risk from attack. If you suspect you have an infection, removing virus threats must be a top priority to protect all your files.

A virus is an evil computer program created to copy itself and integrate itself into the computer. It can spread from the internet or another network, or be carried onto your hard drive with a floppy disk, CD, DVD, or flash drive. The virus can increase its odds of spreading to more than one computer when it can infect files on a network to be shared among many computers. You may notice some obvious changes right away when a virus is at work, but they often work in secret to damage your system or otherwise compromise your files. There are some viruses that reproduce themselves then deliver unwanted advertising or other promotional offers. However, many viruses quietly hide in your system, waiting for a predetermined date when they will become active and begin to destroy files or steal your private information.

Although it is possible to remove a virus manually, it can be difficult to do successfully and will require some knowledge about the threat and some technical expertise. The first step is to find the file that contains the virus and delete it from your system. Then, you must reverse any changes that have been made to existing files, as well as delete any new files the virus has created. You may be able to obtain this detailed information by searching the internet for the virus characteristics. This behavior data is usually obtained in a lab by loading a virus on a test system so all changes can be carefully monitored and recorded. Naturally, with a virus in your computer, searching for the information you need may be difficult or even made impossible.

The best method for removing virus threats is to depend on a top-rated antivirus to scan your system and delete the problem files. There are several good antivirus programs on the market that can do this, but all work in their own unique way, and all offer features that differ from product to product. One of the programs that many people use is PC Tools Spyware Doctor with Antivirus. For software like this, removing virus threats and blocking new ones is exactly the job it was designed for. It works in the background, quietly scanning and watching for signs of of an infection. This program is quick and efficient so you’ll barely notice the program is installed, and it has been awarded Editor’s Choice and Best of the Year awards by leading PC magazines and testing labs from around the world. Plus, they provide free support and regular free updates to be sure you are fully protected from new threats.

Another good option is AVG Antivirus, which provides everything you need for removing virus threats, worms, and spyware. The program stops a virus from making unauthorized changes to your computer so your files stay fully protected. This is a good choice for those that demand good protection, yet don’t want to be constantly bothered with security alerts and pop-ups.

There are, of course, other good choices available as well. Some products are very good, while others seem to be outdated and are generally less effective. Some software titles are available in stores, but if you want a good selection to choose from and you want the lowest price, it is best to purchase an immediate downloadable product online. Specialized security software is the best choice for removing virus threats. With a little research, you’ll be able to easily eliminate existing problems and protect your computer from new threats while getting all the features you need.
