Are you interested to know what is computer virus ? Computer use comes to everyone, and those computer use his virus to be heard must name.
Virus, the name of Internet is a very familiar name in the world. Along with this, it is also a very scary name because it is very harmful for your computer and other electronic gadgets . That is, if it enters the system once , then it can also spoil it and can also destroy your data .
Just like Virus is not good for our health and they spread many diseases in our body, in the same way these Virus also cause many damage in the computer system . Therefore , it is good for all computer users to keep information about them.
So today in this article I am going to tell you about what is a virus and how to kill the virus. Hopefully you will get to know a lot by reading this article.
Computer Virus is a small software program that your computer ‘s operation and the computer ‘s data to delete is designed to or loss reach.
Computer virus without our knowledge can spoil the system in such a way that it is not just for us to fix it. The computer runs through many software programs , without any program the computer cannot work.
Software programs are made to make the computer work properly and some programs are also made to spoil the work of the computer .
The computer was invented by humans , its program was made by humans to run the computer and as I said the virus is also a small program , it has also been made by humans. Computer virus is not natural , it is not made by itself , it is also made by programmers deliberately so that they can spoil other computers .
Or we can say that even the Virus actually computer programs are living in productive rather than destructive means. Its basic purpose is to deliver damage to the place of providing help.
The first computer virus, called “Creeper system”, was an experimental self-replicating virus released in 1971. It was filling up the hard drive until a computer could not operate any further. This virus was created by BBN technologies in the US.
The first computer virus for MS-DOS was “Brain” and was released in 1986. It would overwrite the boot sector on the floppy disk and prevent the computer from booting. It was written by two brothers from Pakistan and was originally designed as a copy protection.
“The Morris” was the first Computer virus which spread extensively in the wild in 1988. It was written by Robert Morris, a graduate student from Cornell University who wanted to use it to determine the size of the internet. His approach used security holes in send mail and other Unix applications as well as weak passwords, but due to a programming mistake it spread too fast and started to interfere with the normal operation of the computers. It infected around 15,000 computers in 15 hours, which back then was most of the internet.
Since then, many new viruses have been introduced and the trend is growing exponentially every year.
What can computer viruses do ?
Computer virus can corrupt or delete the data in the computer . Your hard disk to store the made data can completely drops. Computer virus also spoils their computers by going to other computers through e-mail attachments .
Virus slows down the speed of your computer . It destroys your files and program .
Malware’s full name is malicious software . It is also a software program that gives access to computers . Malicious software means bad software which is not good at all and once it comes in your system , it can completely spoil your system .
Malware is also the name of a virus which starts to slowly erase the data of your system .
Where do Malware come from in our computer ? Malware can come from many places in our system and the most used source which is common source today is internet.
On the Internet , we get some information every day. If we went to any malicious site to get the same information or downloaded pirated software, games and movies from somewhere , then malware online comes into our computer from there .
This was about how online malware gets into our computer , now we will know how offline malware gets into our computer .
Malware is of three types – Virus, Worms and Trojan horse. These three are different, their work is also different. These three spoil your computer in different ways . Let us know about these three and what they do.
Virus can corruptthe files and software in your computer . Suppose your system in a word the document in which the virus has arrived , so that your document ‘s data to delete will or that document the corrupt will give you that any information will not be found.
Or it could also be that this virus can completely corrupt your word processing software . In such a situation, if you copy or share a corrupted file , then this virus goes to another computer and also spoils its system .
Computer virus is a type of malware that if entered into the computer ‘s memory , then it can multiply itself automatically and can also change programs, applications .
Here computer infects occur when these malicious codes keep replicating themselves. Here you people these Computer Viruses of Types I to provide information about.
This type of virus master boot record to infect is to work very been difficult to get them out and often remove them System to Format must. These are mainly spread by removable media .
They are also called non-resident virus , once it is installed , it remains hidden in the computer memory . These those specific type of files to attach these are invariably happens infect does. The user experience and system’s performance to infect do not.
Direct action viruses, such as resident viruses also computer in the install are. Apart from this, identifying them is also a smile.
This type of virus multiple ways the system to affect can. These infect both the boot sector and executable files simultaneously .
This type viruses to identify very been difficult to talk to a traditional anti-virus program to , because the virus ‘s own signature pattern at the time they own when times change replicate do.
This type of virus all files to delete turn that they infect you. To remove these viruses from the system , the user has to delete all the infected files , causing data loss .
These virus detection is very Muskil thing because these emails through the spread are.
Spacefiller Virus – Also called “Cavity Viruses” . They have been given this name because it fills all the spaces in the code , so it does not harm the files .
Some file infector viruses come attached with program files , such as. com or .exe files. Some file infector viruses also infect files with .sys, .ovl, .prg, and .mnu .
In the same way when a particular program is also loaded , the virus also gets loaded automatically. These viruses come in the users ‘ computer with email .
As suggested in the name, these macro viruses mainly target macro language commands only in some applications like Microsoft Word.
These macro viruses from a thus designed has been making these their malicious code can easily genuine macro sequences to add turns.
These virus something that design these themselves which is overwrite any file or application data to destroy can. It starts to overwrite its own code once it starts an attack .
This type of virus is used more often by cybercriminals . These are a type of malware type which easily its underlying code to change or mutate it could do so without any basic functions or features instead.
This does not make it vulnerable to which anti-malware . Whenever anti malware to detect and then does it himself modify the class is so very been difficult to get hold of it.
The virus itself the computer ‘s memory in the implant gives. Basically, there is no need of original virus program for infection to infect any files or program . If ever original virus to delete also give even its a version memory to store happened that the Khudbdkhud activate gets.
This happens when the computer OS some applications or functions to load the. Since it is hidden in the system ‘s RAM , it is often not able to detect any antivirus or antimalware .
The rootkit virus is a type of malware type is that of secretly an illegal rootkit to install makes infected system in. With this, it opens a door for the attackers which gives them full control over the system .
This attacker easily fundamentally a program or function to modify or disable can. The rootkit virus very easily from antivirus software to bypass can. Rootkit scanner is required to capture them .
The Boot-record Infectors executable code to infect the ones disk for specific system areas are found. As the name suggests, they infect more in USB thumb drives and DOS boot sector .
These boot viruses are not seen much these days because the present system does not depend on much physical storage media .
Worms also virus are similar, but they themselves multiply to do and try more spread by itself much. Which means that if there are worms in your system , then they start making many copies of different files , due to which the system slows down.
If the same files to each other that we copy computer with share then worms also go out files lots of copies that make computer too slow will make.
Trojan Horse is a very dangerous malware . These malware come by hiding your identity in your computer .
Suppose you like internet are using and any site to visit to be there you have add , such as showing ” Click Here To Win Laptop ” and the click to be trojan horse malware on your computer come through him Will go and you will not even know about it and your system will completely ruin it.
They also exist on the internet in the form of a lot of software, you will think that it is a genuine software , but in reality it remains a trojan which is hidden inside that software and once they come in your computer , then it will be in your computer. the slow start to. With that, he would open a door so that different kinds of viruses and worms get into your computer .
How to know if your system is infected with Virus or not. That is why I am going to tell you about some warning signs below , which is very important to know for all computer users –
- Slower system performance to be
- Screen repeatedly Pop-ups come
- Own programs
- Files yourself multiplying / duplicating be
- New files and programs yourself computer to install grow
- Files, folders or programs automatically delete and corrupt grow
- Hard drive strange the sound come
If you show such warnings in your system then you should know that your system can be infected by virus . Therefore, soon download and scan a good antivirus software .
How to Own System for Viruses and Worms Top of
Here I am going to give you some such tips that will make it easier for you to avoid these viruses .
1. Your System is always a good bit Antivirus install and to periodically update frequently.
2. Any email if you then sender is no information about when the open should not.
3. Do not download anything from Unauthorized Websites such as MP3, Movies, Software etc.
4. Get all downloaded things scanned well . Because they are more likely to have a virus .
5. Use removable media such as pendrive, only after scanning the disks .
6. If you visit any website , then you should take care of one thing that it is a popular and registered website and do not click on any such link which will cause you trouble later.
What not to do
1. Never open an email attachment , if you do not know about that sender .
2. Any Unsolicited Executable Files, Documents, Spreadsheets , without scan Do not try to be open.
3. Do not download documents or executable software from untrusted websites .
4. Ads which give you greed, click here and win lottery, then never click on such pairs . We get similar greed in our e-mails too, so you should never open that mail as there are more chances of malware in it.
