What is Computer MalwareComputer virus is one of the most devastating threats to the computer world. Like a true biological virus, a computer virus can attach itself to a computer and copy itself.

Viruses are destructive because of the various harmful effects that they can bring to your computer and its files. Data located inside a user’s computer may become corrupted or inaccessible, rendering potentially valuable files useless. Even worse, a virus can completely wipe out the data inside the computer, all of its installed programs, saved files, and created folders.

Computer performance may also slow down, or its applications become inaccessible for use. It is also common to see virus-affected computers crashing from time to time, restarting themselves much to the annoyance of its user.

Computer Malware A virus is actually a computer program itself. Viruses are programs that need to be executed and, once activated, will be able to write their own code to the personal computer’s memory. Most of the time, viruses are able to consolidate themselves with legitimate programs in the form of an executable file, which makes them even more dangerous as the user may mistake a virus for a legitimate file and inadvertently create a virus program. activates.

The types of media to which it can attach itself include binary executable files such as .exe and com files, typical auto-run script files, Word documents, spreadsheets, and database files. Viruses also take up memory due to their nature as a program, and thus take up space that is best used for other important programs.

Viruses can spread through the use of external memory that is plugged into one’s computer, or through the use of the Internet. These programs can make it look like lossy files like images or videos.

The Different Types of Computer Viruses

Computer Malware – Viruses are constantly floating around the Internet because of their ability to replicate. They can make copies of themselves in different types of data files. A virus can start harming your computer the very moment the file it has corrupted is executed. This can cause serious damage to your computer, although other viruses can be just a nuisance and do you more harm than anything else. There are a few different types of viruses and it is important for you to know which are which.

First are memory-dwelling viruses. This type of Computer Malware is not looking to infect other hosts once executed. A memory-dwelling virus waits until the computer user opens the files so that they can corrupt them. They can replicate themselves but do not have the ability to find other hosts.

A non-memory resident is worse then being able to replicate itself, it also has a finder module for other hosts. Once executed within your system it will immediately start looking for other hosts to infect. While the Replication module is corrupting the files, the Finder module is searching for more files to be corrupted. When it finds files to be infected, it instructs the replication module to do so. Once your application programs are infected, the non-memory resident virus takes control of those programs.

The most common type of Computer Malware was the boot virus. This was made possible because the use of floppy discs was so popular. Once executed a boot virus corrupts the boot sector or the master boot record (MBR) of the hard-disk. After infecting one of these, it can be difficult to remove. It continues this cycle by infecting any future disks to be read by the computer. Most anti-virus programs can fix a problem with the master boot record. To remove one of these viruses from your computer you need to get a bootable anti-virus disc, which will remove the boot sector virus quickly and easily.

File viruses are known to corrupt executables of standard DOS, OS/2, Windows and Unix.

Script viruses are like file viruses but are written in the languages ​​used on the net such as HTML, PHP, and JavaScript. A script virus may however be only a small part of a larger virus. They can infect a few different parts of your system as they corrupt any files that allow the execution of scripts.

And finally, macro viruses use macros within applications on your computer to replicate themselves on your system. Macros are commonly used in word processing programs; Macros make recurring tasks easy or automated. These forms of the virus can often spread through e-mail and cause document damage. Although they do not cause as much damage as many of the other viruses discussed here.
