Computer Virus and Its Prevention Methods

Internet attackers are constantly changing, developing new and more intelligent attacks that can bypass anti-malware programs. In turn, anti-virus vendors are then continuously updating their products and programs with new capabilities to detect new malware. To be clear, it has become an arms race, with both sides attempting to outsmart the other. Unfortunately, internet criminals almost always have the upper hand. As such, remember that while anti-malware can detect and block many malware, attackers are always creating new versions that will be missed. As a result, you cannot depend on just anti-malware to protect you. You have to take additional steps to protect

Memory Resident Virus is one type, they usually fix themselves inside the computer memory. They get activated every

2. When an antivirus application identifies a virus and quarantines this file, does this mean the computer is free of the virus and any malicious software?

Antivirus is programming program that outline to make PC gradually in light of the fact that programmer can be take the secret word and furthermore the records can be erase frame desktop and imperative things like video and picture there case about that treats, worms and Trojans.

Let’s say user (A) download an execution file (EXE) on his-her PC and double click on that file, if this file is infected the virus works based on the written code by the hacker/ attacker/ intruder and copy some files into the system. In case, user (A) does not have virus protection, the virus works perfect in destroying that computer or sending information from this computer to the attacker email. Viruses not only designed to destroy PC’s, but also designed to get information from

Computer virus is a program that can copy itself and infect a computer without the permission or knowledge of the user. Viruses perform some type of harmful activity such as accessing private information or corrupting

* They can clean a file system or disk of viruses once they have been found. This is done by scanning a database for established remedies, most antivirus solutions erase a virus immediately and it is expected that the recipient of a virus informs the sender straight away so that the source can be eliminated.

Viruses get into the computer system by many different ways, it can be through downloading infected files online, opening unknown links or downloading attachments files from emails.

Viruses and worms are malicious programs that self-replicate on computers or through computer systems without the user being cognizant. Worms are a series programs that repeat themselves from system to system minus the use of a host fie. Worms use methods to infiltrate remote computers and launch replicas of themselves like email messages or coping files to an accessible disk. A computer virus is a

Computer viruses are minute program which is “embedded inside an application or within a data file which can copy itself into another program“(Adams et al, 2008 ) for the sole determination of meddling with normal computer operations. The consequences may range from corruption and deletion of data; propagation of virus on to network and deployment through attachments through emails in order to further creating havoc to all associated computing devices.

This little package of mayhem consists of relatively few parts. A virus is simply a protein capsule called a capsid, sometimes surrounded by an envelope, containing a genome. The genome consists of nucleic acids arranged as DNA or less commonly, RNA. Dozens of variants of this fundamental arrangement exist with differences in the structure of the capsule and the arrangement of the genome. Small differences or changes in these components allow some viruses to continue to outmaneuver researchers, while millions of dollars are spent trying to understand and eliminate them.

To understand the business of malware, one must understand how malware has evolved in the past twenty-five years. Malware, which includes all kinds of malicious software, was originally created to show the weaknesses of computers. The first type of malware, created in 1986, was a virus called “Brain.A. Brain.A was developed in Pakistan, by two brothers - Basit and Amjad. They wanted to prove that PC is not secure platform, so they created virus that was replicating using floppy disks” (Milošević). Even today malware is still used to check the security of machines.

There are an enormous amount of malicious software programs. The most common types are known as viruses and spyware. Spyware has

There are special viruses that creates different types of malicious problems on a network or computer, for instance it will create or open programs to perform tasks. Viruses is also used for denial of service attacks, password cracking and many more. This can be fought against by having a reliable protection service; it is safer if this is taken from the provider itself.

A computer virus is Program or a portion of the codes that enter into the computer to target vandalism and characterized by their ability to copy itself to many copies and their ability to move from place to place and from computer to computer, disappearances and contents cover.
