Is Spyware Prevention Necessary
Most people believe that once they have anti-virus software installed on their computer, they are adequately protected from malicious intruders into their PC.
This is a serious mistake.
Viruses can ruin your computer, but some spyware can ruin your life.
Some of the more malicious forms of spyware are capable of collecting keystrokes (”key-loggers”) from your computer and transmit them back via the Internet to the cyber-criminals who installed it on your computer without you even knowing it. Another way is that these cyber-criminals can gain access to your computer via a ‘back door’ and obtain your personal information.
The information sent back across the Internet could contain account numbers and passwords to your bank accounts, credit card numbers, including verification codes, and highly sensitive personal information such as your Social Security number. The result is that these cyber-criminals could drain your bank accounts and rack up enormous charges on your credit cards before the banks or credit card companies have time to warn you about unusual activities within your accounts.
In the case where these people get a hold of your Social Security number, they can assume your identity and cause a host of hair-raising problems, such as taking out a mortgage on your house, or even selling your house or conduct criminal activities under your name. I some cases these problems may take years to get straightened out.
Fortunately most of the spyware that can be introduced to your computer is not that malicious. The vast majority of software that is secretly put onto your system consists of small pieces of information, called “cookies” which are designed to keep track of your browsing habits and enable website owners to customize the display and advertisements on their sites according to your fields of interest. Still, these advertising intrusions can also take on annoying proportions in the form of unwanted pop-up ads, useless toolbars and other modifications to your browser’s look.
The best way to protect your computer against this type of unwanted software is to install software that is specifically designed to detect and remove these types of intrusions. There are a number of anti spyware software packages out there, some better than others, but the main key is to make sure that the software you obtain is updated frequently, preferably automatically via the Internet. It is highly recommended that you yourself perform a scan of the computer regularly, at least weekly.
Many anti-spyware packages can be programmed to perform these scans automatically. Usually the default time of such software to do this scan is when you boot up the system first thing in the morning. However, this is also the time you will be most active with the computer, and performing a spyware scan and an anti virus scan could slow your PC down quite a bit. It might be better to schedule these scans to be run during off times, such as lunch or dinner hours when you least use the computer.
Scanning the computer only removes the nuisance software after it already has been installed. It is of course much better to try to prevent such intrusions before they happen.
One way is to not to plug your computer directly into the modem, but install a router between your modem and your PC. This will stop many of the attacks, but not all of them. In addition to that, the installation of a firewall presents an extra barrier to intruders. Also, make sure that you regularly update your operating system, as many of the security leaks of the software are constantly being addressed and fixed.
None of these preventive measures are foolproof, but if you combine all these techniques, you may be spared a lot of grief and annoyances.
