Is Windows Defender enough for Windows 10?

How Do They Create Virus?
A computer virus is nothing but a type of application like any other software. A programmer, who can develop a computer software is also able to form a computer virus. Like other software, a virus is also just a compiled application designed to run on your computer. However, the difference between a virus and a software is that the virus is designed to harm your machine through various means like crashing on your computer, wiping the data, steal confidential information like credit card number, SSN, etc. A compiled application is formed of bits, and the application compiles into the same sequence of bits every time as long as the code isn’t changed. Now, this sequence of bits is referred to as ‘Signature’ in the world of the virus. When a virus invades a computer, it follows the same signature as it passes from one computer to another. This same sequence of bits is what helps antivirus developers to recognize it as a virus when on a computer. Sounds easy to catch a virus, right? Well, it is not as easy as explained. Viruses are made hard to find by creating different variants and adding them to existing virus signatures. If you perform research, you may find that one virus has multiple names. It happens when a developer takes the existing virus code and alters it to his own specifications before compiling and spreading it. Now that most of the code for the virus is the same as the original virus file, the new modified version would have a similar but a little altered signature.
How Does Antivirus Work?
Now that you know about a virus signature, this is how antivirus software works to find and neutralize it. An antivirus program takes the help of its own database of virus signatures. This database is what your antivirus software is all about. Your antivirus software employs a database of virus signatures and searches for executable files for these signatures. You may understand this process through an example, where a file named info.exe’ is on your computer, which is a virus disguised as an authentic file. The antivirus tool scans this executable file against its database of signatures and blocks the program if a match is found.
Why Do You Need Antivirus Software?
Antivirus programs are designed to protect your computers and other devices from all the malicious tools like virus, Trojan, and worms. The virus is a type of malware that once on your computer, may sabotage the entire processing unit by manipulating your system. The virus attack may also cause a system collapse, where you may lose every piece of information saved on your machine. Moreover, spyware on your computer may steal your confidential information like credit card numbers, Social Security Number, banking credentials, etc and transmit them to someone you don’t know. When you have an antivirus software, you minimize the risk of having a virus on your computer to an optimum level. Nowadays, antivirus software not only provides you protection from viruses but also offers a real-time shield that also takes care of your web security and USB drives. Considering the present era or revolution in information technology, antivirus software is as important as an operating system for your computer. However, it is important that you don’t fall prey to those malware that disguises as antivirus. Ensure that you’ve checked the “Checkmark Certification” on the tool’s official website.

I’ve a Mac. Do I Still Need Antivirus?
The shortest answer to this question is ‘yes’. Mac machines are not immune to virus and malware. You must know that Mac-targeted attacks have been increasing prevalently.
