Computers have really changed our way of life, but they are still prone viral intrusion. As their importance is growing, good protection for them is also required. A virus can enter a computer via a storage medium which carries contaminated data and contact with the system. If a computer is connected to a network, the chances of penetration of the virus to become very high if it is not protected by antivirus software effectively. The Internet has changed the method of communication throughout the world and now appears as an area without borders. In this scenario, the chances of penetration of the virus into a computer connected to the Internet has become very high.
What is a computer virus?
A computer virus is a virus that infects the human body. A virus is a program that can replicate itself and infect a computer. A computer virus is also known as malware, or malicious. There are many types of malware that can also produce themselves but can infect your computer. If the files on the network file system to be infected with computer viruses, the chances of spreading the virus becomes very high because the file system is also accessible from other computers.
What is antivirus software?
Antivirus software is software that can detect and remove viruses from your computer. The virus removal programs use two common methods to detect viruses. One way is to use a list of virus definitions. In this method, the contents of computer memory (RAM and the boot sector), the files stored on fixed drives or removable media (floppy drives, hard disks) are tested, and then the files are compared against a database of signatures known viruses. This method provides protection against computer viruses, only those with the virus signatures are stored in a database.
The second method is based on the heuristic algorithm to identify viruses based on common behaviors. This method is more efficient because it can detect the new virus, antivirus, security vendors have yet to create a signature for.
A user can download and install Internet security software to protect your system. There are many vendors that offer solutions against different types of security threats against computer viruses. Some names like Avast, McAfee, Norton and Kaspersky are very common virus removal software.
Although it is very easy to download and install the antivirus program, but this must be done under the supervision of an expert. There are several things that must be reviewed before installing this software on a computer. First, make sure your computer is not infected with any virus. Virus removal software might not work on a computer is already infected by viruses. Some types of computer virus mimics the behavior of different files, the antivirus software may not be able to detect them.
