Computers have indeed changed our way of life, but are still prone to virus intrusions. Its importance grows as adequate protection for them is also necessary. A virus can enter a computer through any data storage device that transports data between the infected and in contact with the system. If a computer is connected to a network, the chances of intrusion by viruses be very high if not protected by antivirus software effectively. The Internet has changed the method of communication worldwide and now appears as an area without borders. In this scenario the potential intrusion of viruses on a computer connected to the Internet have become very high.
What is a computer virus?
A computer virus is a virus that infects the human body. A computer virus is a program that can replicate itself and infect a computer. A computer virus is also known as malicious software or malware. There are many forms of malware may also not be repeated but can infect your computer. If files on a network file system is infected by computer virus, the risk of spread of the virus is very high because the file system is accessible to other computers as well.
What is antivirus software?
Antivirus software is a program that can detect and remove viruses on a computer. Virus removal software uses two common methods of virus detection. One method is to use a list of virus signature definitions. In this method, the contents of computer memory (RAM and boot sector), the files stored on fixed or removable drives (floppy disks, hard disks) are examined and compared the files with the virus signature database known. This method provides protection for your computer from viruses of which only the virus signatures are stored in the database.
The second method is based on heuristic algorithm to find viruses based on common behaviors. This method is more effective because it is able to detect new viruses, anti-virus security vendors have yet to create a signature.
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.
