Protect your computer from nasty email viruses by reading this article!

Viruses are to computers the same as viruses are to humans, ina way. A virus in a human can interfere with the natural working processes of the human body. A computer virus can interfere with the internal workings, namely the hard drive, of your computer. Both viruses can usually be avoided by using antivirus prevention. Your medical doctor can vaccinate your body against many types of viruses. You can install antivirus software on your computer so it will be vaccinated ina sense, and effectively keep your computer free from damaging viruses.

Computer viruses are made simply to wreak havoc in other people's computer systems. Some viruses are not harmful, but rather, they install themselves on your computer. Once installed, they follow their programmed instructions and make your computer do some things that are out of the ordinary. These range from strange pictures popping up on your computer screen, to opening the CD-Rom door, to making your computer screen suddenly go blank at various times. Harmful, no, but they can definitely be annoying.

Other viruses are made to be harmful and destructive. Some viruses can delete entire files from your computer's hard drive, destroy programs, or part of programs, reproduce itself and spread, and literally shut your computer system completely down.

Most antivirus programs recommend that you should protect the data that is on your computer's hard drive by creating master back up diskettes. Back up diskettes will allow you to restore your computer to its original condition. This will be necessary to do in case your computer system contracts a virus and the system is damaged or changed in any way.

Experts recommend that you only purchase software from a reliable source that you can trust. Viruses can easily be transmitted from one computer to another by sharing diskettes as well as other software. Using public computers can be okay, such as the computers at the local public library, but be careful if you copy data onto a floppy diskette. Run a virus check on the diskette before you use it in your computer. In fact, you should be this cautios with all floppy diskettes you use in your computer.

Viruses can be passed from one computer to another by means of e-mail too. Experts recommend that e-mail users do not open any mail that is sent to you that you're not sure where it came from. Avoid opening any e-mail attachments that look suspicious too, like a VBS file. This has attachments and the letters .vbs on the end of the file name. This type of file extension means that the file is a script program. Normally, no one would be sending this type of fiel to you unless it had a computer virus attached to it. E-mails with attachments that end with the extensions of .vbs, .exe, and .com should all be opened with the utmost caution as these files can contain programs that have computer viruses on them.

Once a virus is found on your computer, it must be totally eliminated at its source. After the virus is eliminated, usually by some sort of virus killing software, the entire system must be scanned and examined carefully to make sure that the virus did not spread to other parts of the computer system . For example, if you find that your computer has a virus on a floppy diskette which is in the A drive,then you must scan the entire system to make sure it did not spread to your hard drive. Your hard drive needs checked too, to make sure it still operates properly.
