All of these are bad news for any computer users and have a varying level of danger. There are thousands of different types of virus; some designed simply to send you mass advertising and spam to others that are interested in logging every single key you press on your computer.

A virus program uses a variety of methods to protect your computer from this threat. Most virus checkers offer full scans as well as scanning in real time to watch out for any incoming problems. If you’re concerned you might have a virus, a full scan will let you know.

Likewise, if you’ve downloaded a file that contains a virus, most antivirus software will tell you straight away so the virus can be removed before it has a chance to infect your system.

Using an antivirus checker is a personal choice although almost every security expert and almost all ISPs agree that the software is vital. You might think you don’t need antivirus software because you don’t download, but modern viruses and exploits in your operating system mean that you don’t actually have to download anything to become infected. Viruses can travel across your network from one computer to another, just like they do on the internet.

The disadvantages of antivirus software are the heavy use of system resources and the cost of the package. However, antivirus software is a competitive market causing companies like Zonealarm to bundle more and more products in their security software while reducing the price.

Although many of the severe viruses can be avoided by keeping your operating system updated and using a firewall, antivirus software is a far more serious barrier. Money spent today could save you serious problems in the future, from having to pay someone to fix your computer after an attack to having your financial details stolen and sold on to a third party.

It’s important to mention that antivirus software can never guarantee to stop every single attack. New viruses are created frequently and it takes all software some time to catch up.

As with most forms of internet security it’s not about trying to make your computer impossible to attack, it’s about taking sensible precautions to make sure an attack is very unlikely and you can deal with the affects.

Buying an internet security suite and keeping it updated as often as possible is one of the most important things you can do to protect your computer, as well as your own personal information and data.

With some broadband deals, you may get a security suite, but with cheap broadband packages, you may find this is not the case, or that the security suite is just a free trial.
