know most of the people who start off reading this really have no idea what the difference is between a virus, worm and Trojan Horse. Most people really don’t care as long as they do not have to deal with any of these malicious applications. Fair enough, however being knowledgeable of these types of nuisances can help you in your quest to prevent them. So please read on to help you better understand how to tell the difference between a virus, worm and Trojan Horse.

Computer Virus

A computer virus is a program or piece of code that is actually loaded on your computer without your permission or knowing and runs against your wishes. Some viruses are only made to be a nuisance, while others are simply out there to destroy. Some viruses can literally damage all your hardware, software and files on your computer. Almost all viruses are attached to an executable file, which means the virus is on your computer but it has no power to do anything unless you open or execute that specific file. 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 email.

Worm

A worm is a program or algorithm that can duplicate itself. A worm has the capability to travel without any help from a person from PC to PC and have ability to duplicate 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 massive problem for you and people you are sending infected files to. Its like a true infestation.

Trojan Horse

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.

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.

They install tons of uncecessary software to your computer to assist them in their never ending quest for money grabbing. Please check out this anti-virus below, it will work MUCH better for you!

  • Back up your files. Viruses are one more very good reason to always back up your files.If you back up a file that is already infected with a virus, you can re-infect your system by restoring files from the backup copies. Check your backup files with virus scanning software before using them.
  • Keep your original application and system disks locked (write-protected). This will prevent the virus from spreading to your original disks.
  • If you must insert one of your application disks into an unknown computer, lock (write-protect) it first, and unlock your application disk only after verifying that the machine is virus-free.
  • Obtain public-domain software from reputable sources. Check newly downloaded software thoroughly using reputable virus detection software on a locked floppy disk for any signs of infection before you copy it to a hard disk. This can also help protect you from Trojan Horse programs.
  • Quarantine infected systems. If you discover that a system is infected with a virus, immediately isolate it from other systems. In other words, disconnect it from any network it is on and don’t allow anyone to move files from it to another system. Once the system has been disinfected, you can copy or move files.
  • If you use a desktop version of Outlook, minimize use of the preview or reading pane feature.
