There is a continuous development of computers and intent technologies but in the mean time all these developments  on one side leads to the development  in the various fields  for example  education , communication and  business, but  on the other  side it caused several  threats  on the Internet such as virus, trojan horse, worm, and spyware .But before discussing on the process to get rid of these  threats, we need to understand what exactly these threats are and how they spreads.A virus is a program or code that copies itself into other programs, it execute itself and replicate itself. Virus can infect desktop and network server, some viruses are programmed to damage the computer by damaging programs deleting files or reformatting the hard disk. Others are not designed to do any damage, but simply to replicate themselves and make their presence in video, and audio messages. These viruses can create problems for the computer user. They take computer memory used by important programs, these viruses can crash your system and slow your computer or even some times freezes the computer . Viruses are of many kind and they infected different files like file infector viruses. These viruses normally infects executable code, such as .exe and .dll  files. They can infect other  files when an infected program is copied  from floppy, hard drive or from the network . Boot sector viruses infect the boot record on floppy disks and hard disks. All floppy disks and hard disks  contain a small program in the boot record that is run when the computer starts up. Boot sector viruses to this part of the disk and activate when the user attempts to start up from the infected disk these viruses responsible for slow booting of your computer. Master boot record Master boot record viruses are memory-resident viruses that infect disks in the same manner as boot sector viruses. To repair computer infected by virus you need antivirus.Worms are almost similar to that of the virus. Unlike the viruses, worm uses computer networks to replicate itself.  It searches for servers with security holes and copies itself .Worms are programs that replicate themselves from system to system without the user. This is in contrast to viruses which requires the spreading of an infected host file, However worms generally exist inside of other files often Word or Excel documents, there is a difference between how worms and viruses use the host file. To remove all these threats from our computer, we need to download and install antivirus software on our computer. But we have to keep one thing in our mind, that installing antivirus software never means that our computer is free from all the threats, as these virus worms are created on the daily basis, so to make our computer immune against all these new threats, we need to update our antivirus software, we can download these updates form the websites of the antivirus software.So if  we scan our computer, with the updated antivirus softwares atleast once in a weak, we can make our computer safe and secure against all the threats.

Computer viruses have been a source of trouble for individuals and businesses for decades. Their malicious strength ranges from mildly annoying to incredibly destructive. In some cases, they can wipe out entire computer systems, or even whole networks if durable enough. To know how to properly combat these vicious foes, you must understand how a virus functions and some of its basic properties and characteristics.
Viruses are computer programs, designed by an individual or team to infect a device without the user becoming aware of the breach. The main purpose of a virus is to corrupt the files of a computer and ultimately render the system useless. Many viruses are launched by hackers simply for their own personal entertainment; in fact, some of the most malicious viruses in history have this root. Sometimes, the goal is more productive, such as wanting to destroy a competitor’s computer network to make one’s own business stronger.
People often get confused as to the differences between viruses, worms, adware, malware, and Trojan horses. The defining characteristic of a virus is that it needs to attach itself to a program, or host, in order to replicate and spread. Worms, on the other hand, can survive on their own without a host. Adware does not exactly have a malicious intent, although few computer users want it on their systems, as the software displays advertising even when the user is not on any web pages.
Trojan horses appear to be harmless files, but actually open the door to hackers to further devastate or commandeer a node. Malware is an umbrella term which covers everything previously mentioned, plus unique software which does not fit the characteristics of other programs but is still malicious.
The best way to avoid viruses is to not receive them in the first place. You can steer clear of the majority of viruses by simply being careful. Being careful includes not opening spam emails, not downloading programs you are not familiar with, and putting strong passwords on to all of your computer accounts. If you take a strong amount of caution in all of your computing activities, there is a good chance you will not ever have to deal with a virus-related problem.
However, sometimes infections are unavoidable. Viruses travel from file to file, corrupting each one, and they travel from computer to computer when one of those corrupted files is sent out. A friend or coworker could unknowingly send out a corrupted file, thus infecting every recipient.
Businesses have become aware of the consumer and industrial need for virus protection. Several companies, such as McAfee and Avast, sell anti-virus software which automatically scans for viruses, worms, and every other type of malware. Whenever the program finds something particularly strong, it notifies the user and offers them several options, such as deleting or quarantining the threat. Garden variety viruses are rooted out in daily scans, and although these kinds of viruses may not be serious, they do inhibit the operational speed of any computer.
Anti-virus programs must be updated on a regular basis, so the software’s registry can be filled with new virus signatures, which are unique strings of bits inherent to different viruses. Certain viruses are labeled as metamorphic, in that they change each time they are copied, making them hard to track. As long as your anti-virus software is kept up to date, you should be able to contend with anything that is thrown at you. make your own website

Because new viruses are created constantly, virus protection is never guaranteed, but an updated virus protection software is preferred as you will be protected from new viruses discovered by the manufacturer of the virus protection software you use.

Free virus protection software are often very good, but you should keep away from the scams. To understand why you need a paid or free virus protection, it would be better if you know what a virus is, and how it works. The best way to learn that is actually to be infected by one. We are not going to learn you how to get infected, instead how you best avoid that to happen.

You could be infected right now, totally unaware of it. An email with an virus attachment could also land in your mailbox, and when you open this attachment your computer will be infected. Sooner or later, you’ll receive an email like this. If you have either a paid or a free virus protection, this email should be cleaned, quarantined or deleted. If you don’t have any

protection, you might be in serious trouble.

A virus could be created to do numerous of different things to harm your system. It is a piece of code with the ability to duplicate itself over and over again. A computer virus could for instance cause your telephone bill to show charges for calls made to porn sites, or other suspect sites. Although you are absolutely positive that you have never been on those porn

sites, or anything similar, the charges still appear on your phone bill. What we are talking about here is a so-called “Dialer” -virus. These works with dial-up connections.

Other viruses are made to erase your system files, and the result is a total shutdown of your entire computer system. Viruses could practically do anything they want to. Which intentions the different viruses have, is solely determined by their creators.

So, how do we protect ourselves and our computers against these malicious threats? Well, it has become an endless job to keep systems protected and updated to shield them from the latest threats. No virus protection software, free or paid, knows every virus out there, and there are a large variety of products when it comes to numbers of known virus signatures, and its

ability to find and remove the threats.

Many of the largest virus protection manufacturers are known for having a large signature database, but unfortunately it seems that they are not always the best ones to remove the viruses. What I personally value most when it comes to both paid and free virus protection software, is the software’s ability to find viruses and destroy them, but also that it runs on little system resources. This way you could still run a virus check, and continue to use the computer as you did.

Here is also a lot to choose from, but I will recommend you one piece of free virus protection software that you can test for yourself. It is an open source project started to make private users contribute to the development of this software. It runs on little resources, has a good signature database, and best of all, it’s free. FreePcAssistance.com is a website dedicated to computer security. We evaluate free and paid security software for private users.
