Any kind of computer virus is dangerous mainly because it uses up storage and brings your system to a total stand still.

The worm is similar to a computer virus with the point that it is self-replicating but differs in the point that it does not have to have an additional application to do so. A worm can easily distribute on its own without any actions from the individual. A worm might connect itself to your address book and deliver a replica to everybody inside it, after that attaches itself to the receivers address book as well as in addition, sending itself out to everyone inside that address book.

Today, more and more people are using their computers for everything from communication to online banking and investing to searching. As we do these things on a more frequent basis, we open ourselves to prospective hackers, attackers and crackers.

While some may be looking to phish your personal information and identity for resale, others want to use your computer as a platform from which to attack other unsuspecting targets. Hereunder are a few easy, cost-effective steps you can take to make your computer more secure.

1. Always make backups of important data and store it in a safe place away from your computer.

2. Update and patch your operating system, web browser and software frequently. If you have a Windows operating system, start by going to windowsupdate.microsoft.com and running the update wizard. This program will help you find the latest patches for your Windows operating system. Also go to officeupdate.microsoft.com to locate possible patches for your Microsoft Office software.

3. Set up a firewall. Without a good firewall, viruses, worms, Trojans, malware and adware can all access your computer from the Internet with no trouble. Consideration should be given to the advantages and differences between hardware and software based firewall programs.

4. Review your browser and email settings for maximum security. Why should you do this? Active-X and JavaScript are often used by hackers to plant malicious programs into your computer. While cookies are relatively harmless in terms of security matters, they can still record your activities on the Internet to build a profile of you. As a minimum precaution, adjust your security setting for the ?Internet zone? to High, and your ?trusted sites zone? to Medium Low.

5. Install antivirus software and set for automatic updates so that you receive the most recent versions.

6. Do not open unidentified email attachments. It is simply not sufficient that you may know the address from which it originates because many viruses can be spread from a familiar address.

7. Do not run software from unidentified origins. Also, do not send these kinds of programs to friends and coworkers because they contain funny or amusing stories or jokes. They may contain a Trojan horse just waiting to infect a computer.

8. Disable hidden filename extensions. By default, the Windows operating system is set to ?hide file extensions for known file types?. Disable this option so that file extensions show in Windows. Some file extensions will, by default, continue to remain hidden, but you are more likely to see any strange file extensions that do not belong.

9. Turn off your computer and disconnect from the network when not using the computer. A hacker can not attack your computer if you are disconnected from the network or the computer is off.

10. Make a boot disk on a floppy disk or CD in case your computer is damaged or compromised by a malicious program. Obviously, you need to take this precaution before you are subject to a hostile breach of your system security.
