Types Of Computer Viruses And Worms You Probably DON’T Know!

Computer viruses are created for infecting the information and the rest of the computer. It is actually a computer program that is intended to create such uncertainties. The first theories on computer virus were done by John von Neumann in the year 1949. Since then the computer viruses have been a menace to the computer users. Some of the impacts that the computer has on the computers are impairment of certain computer programs and applications after which you may not be able to employ the software. There are also some viruses that are meant to corrupt a few files that may be important for your business, etc. There is also a possibility for the system to crash as well. Here are a few popular types of computer virus.

Resident Viruses

This is a type of virus that stays permanently in the RAM memory. It is from this memory that the interruptions of the rest of the computer programs are affected. It can be compared to the direct payload virus as it does not insert itself into the system’s memory but takes action only when an infected file is executed.

File infector virus

This virus, as the name suggests is the type of virus that is meant for the infection of the file. This infector takes refuge in the host and then works out when the file is executed. The file may either be overwritten or a few parts being replaced.

Boot virus

The hard disk or the boot drive of the computer is affected due to this virus which forms the important part of the computer where the whole of the information is stored. One of the best tips on how to prevent computer virus of this type is to make sure that you use write proof floppy disks and remember not to start your computer with an unknown floppy disk in the drive.

Macro Viruses

These types of viruses are generally scripted into common application programs like Excel and Word to infect the other documents. The program is not written in the language of the operating system but that of the application. The macro virus spreads to the other parts when the application is running. There are numerous macro viruses present and each of them is a great threat.

Worms 

This is also a program that makes and distributes the copies of itself from one disk drive to another or using emails to copy themselves and transport the mechanism. These can cause serious threats to the computer security.
