Although numerous in their design, computer viruses can basically be broken down into two categories. These include a virus that can either be destructive or simply annoying. In order to combat both, software developers have created anti-virus software that is designed to detect and remove certain types of computer viruses, along with worms, spyware, adware and identity theft.
With modern technology having turned toward computers and the internet, computer viruses are more problematic than ever. While anti-virus software is important, the best approach to fighting against a computer virus is knowing how to avoid one. Here are a few tips:
Never download an e-mail file from anyone that you do not know. Whether it be a document, photo or other program, simply close the e-mail without downloading it’s contents.
When visiting websites, carefully select reputable companies when downloading files. This may include e-books, freeware, software, photos and other programs. If you are not familiar with the company or the website, there is no way to know what you will be accessing and how damaging it may be to your computer system.
If you choose to download either an e-mail or internet file, use your anti-virus software to check the file prior to opening it on your computer.
Always keep your anti-virus software updated with the latest information and upgrades from the manufacturer. When it is time to replace your software because it is outdated, don’t wait. New computer viruses are created often and no system is truly safe without some type of updated detection software.
As mentioned earlier, a computer virus can be either damaging to your computer system or may be nothing more than an annoyance. An example of a destructive virus would be one that destroys your hard drive files, prevents your computer from continuing to operate or may cause you to have to re-install the computer’s configuration using the Restore CD that accompanied your purchase. An annoying virus may cause your computer to operate slower than usual or may prevent certain files from working properly.
In some cases, software manufacturers create programs that have ‘bugs’ within the program. This is often called a virus, but should not be considered in the same manner as a typical computer virus. The reason is because a software manufacturer does not create these ‘bugs’ to intentionally hinder their customers and will generally work to replace the faulty program. In addition, a software glitch will not prevent your entire computer from operating or delete all of your files from the hard drive.
Common sense, along with an anti-virus program, will go a long way in both detecting and avoiding a computer virus. Without these important elements, your entire computer system and the information on it are at risk of infection.

Tips and recommendations for protecting your PC...
Most of us don't make a real difference between worm, virus and Trojan Horse or refer to a worm or Trojan Horse as a virus.
All of us know all are malicious programs that can cause very serious damage to PC. Exist differences among the three, and knowing those differences can help you to better protect your computer from their often damaging effects.
A computer virus is a program or piece of code that is loaded onto your computer without your knowledge and runs against your wishes. Some viruses cause only mildly annoying effects while others can damage your hardware, software or files. Almost all viruses are attached to an executable file, which means the virus may exist on your computer but it cannot infect your computer unless you run or open the malicious program. A virus cannot be spread without a human action, (such as running an infected program) to keep it going. People continue the spread of a computer virus, mostly unknowingly, by sharing infecting files or sending e-mails with viruses as attachments in the e-mail.
A worm is a program or algorithm that replicates itself. A worm has the capability to travel without any help from a person from PC to PC and have ability to replicate itself on your system, so rather than your computer sending out a single worm, it could send out hundreds or thousands of copies of itself, creating a huge devastating effect.
A Trojan Horse is a destructive program that "working" as a benign application ( (like changing your desktop, adding silly active desktop icons) or can cause serious damage by deleting files and destroying information on your system. Trojans are also known to create a back door on your computer that gives malicious users access to your system, possibly allowing confidential or personal information to be compromised. Trojans do not reproduce by infecting other files nor do they self-replicate.
Added into the mix, we also have what is called a blended threat. Blended threats combine the characteristics of viruses, worms, Trojan Horses, and malicious code with server and Internet vulnerabilities. By using multiple methods and techniques, blended threats can rapidly spread and cause widespread damage. Characteristics of blended threats include: causes harm, propagates by multiple methods, attacks from multiple points, and exploits vulnerabilities. This combination of method and techniques means blended threats can spread quickly and cause widespread damage. Characteristics of blended threats include: causes harm, propagates by multiple methods, attacks from multiple points and exploits vulnerabilities. They are considered to be the worst risk to security since the inception of viruses, as most blended threats require no human intervention to propagate.
Therefore is very important to protect your PC with a good anti-virus software installed on your system with the latest fixes for new viruses, worms, and Trojan horses.
Additionally, you want to make sure your anti-virus program has the ability to scan e-mail and files as they are downloaded from the Internet. This will help prevent malicious programs from even reaching your computer. You should also install a a system that prevents unauthorized use and access to your computer (firewall as well). A good software firewall will protect your computer from outside attempts to control or gain access your computer, and usually provides additional protection against the most common Trojan programs or e-mail worms.
