What Is Antivirus?
An antivirus is a software used in the prevention, detection, and elimination of malware that attack a computer or mobile phone. The term malware is used to define attacks such as worms, viruses, Trojan horses and spyware. It was initially started to provide the necessary protection from other threats affecting a computer. The modernized versions of anti-viruses offer various kinds of malicious activities, ransomware, and keylogger, rootkits, worms, dialers, adware, Trojan horses, fraud tools, malicious LSPs, and spyware.
Some of the other products that are available in the market offer protection from infected and malevolent scam spam and attacks. They also provide protection from phishing, online privacy identity attack, and even advanced persistent threat.
Incidents of viruses attacking computers started in early 1949 when a scientist known own as John Von Neumann printed the theory of self-reproducing automata. The first sited computer virus was detected in 1971 and was called the creeper virus. This virus infected the digital corporation equipment mainframe computers that were running the operating system TENEX.
The creeper was first eliminated by a program known as the reaper, which was created by an individual Ray Tomlinson. The creeper was later trailed by others types of viruses developed. Before the internet was relatively popular, the viruses were initially spread by the floppy disks. However, as the internet use started growing, the viruses were now spread online. Many of the innovators have over the years competed on being the first to develop the antivirus.
Over the years there are several people who have developed some antivirus software. In 1987, John McAfee of USA founded anti-virus scan company known as McAfee Company. In Hungary, a security researcher developed the first Pasteur antivirus. Currently, the industry is facing some problems in detecting and dealing with the zero day attacks. However, they are trying to find other ways of dealing with the issues.
Bromium has developed micro-virtualization that enables the protection of desktops from the attacks of malicious execution code which is initiated by the user. As more viruses are being developed and the internet connectivity becoming popular, updating of antiviruses has become a necessity.
For antivirus companies to deal with the malware, they have to develop more multifarious algorithms. Recently antivirus softwares have adapted the use of different strategies, for example, network protection, specific email protection, low modules level protection, and detection algorithms looking at the increasing number of the various infective files. There are numerous reasons as to why this is done such as;
- The powerful macros that are used in word processor bids such as Microsoft word. The viruses coders [writers] can use the present macros to write the viruses found within the documents. It means that the computers used could also be easily infected through the opening of the documents which have the macros.
- The possibility that executable objects that are within the otherwise files that are non-executable can lead to risky situations in opening the files.
- Email problems later on, in particular, the outlook Microsoft and express. These are highly vulnerable to the viruses within the email body in itself. A person’s computer could be easily affected by simply opening or even previewing a message.
How an antivirus functions
Traditionally, an antivirus software relies so much on signatures so as to enable malware identification. When a malware is detected, it is carefully analyzed by a team of researchers. Then afterwards, a proper type of monogram is developed and added onto the signature existing database of antivirus software.
It functions like the immune system. It has to scan your computer and device for signatures that are known to be malevolent. It sometimes matches the monogram malicious patterns and attempts to counterbalance it. It has to protect the computer against what is recognized to being harmful.
The problem is that the malwares cyber attacks are coming up so fast that antivirus innovators are finding a hard time keeping up with the development. The other way it functions is through behavior detection. It will not attempt to identify the malwares but will rather closely monitor the performance of the software, which has been installed on your computer.Sponsored Links
When a program tries to act suspiciously for instance trying to gain access into files that are protected or to go further as to modify a program, the antivirus is programmed to alert you. This approach has an advantage because it protects against even the new current malware.
The disadvantage comes in that it can bring about false warnings. As the computer user, you are allowed to desensitize those warning overtime. An antivirus is really important in securing your mobile device and computer. It is highly recommended for one to install it and use it properly. However, it is important to note that an antivirus cannot protect one from all types of malware. You should really be careful to what you expose your computer to.
You should obtain anti-virus from vendors who can be trusted. It is usually common practice for cyber attackers to fake programs of antiviruses that are malwares.
- Make sure you purchase the latest antivirus software, pay the subscription needed so as to frequently update the software. It’s advisable for you not to postpone the updates when you connect the computer to the internet.
- Ensure that you install antivirus scans for all the portable media like usb sticks, always make sure that the real time fortification is on.
- It’s recommended for one to pay attention to all the displayed warnings on your screen and alerts engendered by the antivirus software.
- Avoid uninstalling your antivirus or disabling it because you think it is affecting your computer speed or it prevents you from downloading and installing other programs. This practice exposes your computer to a lot of unnecessary risks.
- Avoid the installation of numerous anti-virus programs at the same time. This may cause the rising conflict of the programs therefore reducing their effectiveness
- It’s always good for one to recognize the original antivirus software. Many cyber attackers post fake but seemingly realistic antivirus warnings. If you click on them, they may damage your computer.
