Computer viruses, which are known as one of the major threat to computer user. The purpose of a computer is to process data by which we can create information. The goal of computer security is to protect this process.

As data and information are intangible, computer security is difficult. Despite this, everyone should try to protect everything of value from every threat they can identify. There are various categories of computer threat but in this article we will discus about computer viruses.

What is computer viruses?

Virus stands for Vital Information Resources Under Seize. It is named by a researcher Fred Kohen.

Computer viruses are programs which lies themselves with other useful program, spread themselves and causes harm to other useful programs. The affected programs also work as a virus after affected by virus and they again help the virus to spread all over the computer.

What a virus can do to our computer?

Can a virus make any harm to hardware?

The theoretical answer for this question is ‘yes’. Computer virus is a program. It can come in contact with another program and stay with other program to spread itself. As a program can interface with hardware then computer viruses also can interface with hardware and can make harm to hardware.

How can understand that computer is affected with virus?

We can make a decision that my computer is affected with viruses by observing following issues;

How to keep a computer viruses free?

Antivirus, Remove all threat to computer

Antivirus is created for removing the computer virus and all threat to computer. Antivirus has been kept update to detect newly generated virus.

It is very intellectual, time spending and expensive task to keep them up to date as there are many new viruses is generating every day from different places of the world. For this it is not possible to make an antivirus without a large company.

Some of the popular antivirus program

1. Bitdefender antivirus

2. Norton antivirus

What is virus scanning

To determine the existence of computer viruses inside the computer and its destruction is called virus scanning. Scanning can be done by any antivirus after installing it.

If the virus guard is activated then the guard come to the memory when we start the computer and guard against virus. We can scan virus by running our antivirus program if the virus guard is not set to activated.

Keeping your PC up to date

PC hardware and software are becoming increasingly complex. For this it is becoming increasingly important to do regular maintenance of them.

This means defragmenting your hard disk, checking for computer viruses and performing other basic housekeeping chores to keep your machine active. Runtime system maintenance includes updating important system and program files.

Make sure that your system software is kept up to date. By this, you reduce the risk of system failures and keep your programs running as well as possible.

Device drivers provide a good example. Suppose, you update your operating system, then your CD-ROM drive begins functioning properly. You might be able to fix this problem by installing an updated device driver that is more compatible with your operating system.

You don’t need to call a PC technician to update critical system files of your personal computer. Thanks to a new breed of automated websites, you can sit back and let your PC update itself.
If you are a registered user of Microsoft windows or Microsoft office, for example, you can visit Microsoft product update web sites and download bug fixes, patches, updated system files, templates, security related files and much more. You can visit the windows update site at http://windowsupdate.microsoft.com.

Updating is extremely important. Without the latest computer virus definitions, your antivirus software can’t protect your system against the latest computer viruses.

If you use any kind of high-capacity storage device, you can probably visit the manufacturer’s web site for updated drivers and utilities that can make your drive easier to use or more functional.

If you have purchased new computer, operating system, application, or peripheral, and if the product is from a major manufacturer, there’s good chance, the product offers online support of some kind.

To learn what options are available for your specific products, check your online help systems and printed documentation. Look for web addresses for software update, download, or support pages.

How often should you update?

It depends on the software. If you use a new version of windows, you should configure to check for update whenever you are online. That way you won’t miss a critical update, which could compromise your system’s security.

Check for updates to your antivirus software definitions at least once a week to keep your system free from computer viruses. If your antivirus program can receive updates automatically, set it to do so.

Otherwise, it’s good idea to check for updated device drivers and support files occasionally, to keep your peripheral devices and other programs running as well as possible.
