The Top 10 most dangerous computer viruses of 2020
As the world grows more interconnected, the risk of a computer virus infecting systems around the globe increases. While there are many different types of computer viruses, some are more dangerous than others. Here are the top 10 most dangerous computer viruses of 2020:
1. WannaCry
WannaCry is a ransomware virus that was first discovered in May of 2017. It quickly spread around the world, infecting more than 230,000 computers in 150 countries. WannaCry encrypts files on an infected computer and demands a ransom be paid in order to decrypt the files.
2. NotPetya
NotPetya is another ransomware virus that first emerged in June of 2017. It shares many similarities with WannaCry, including the way it encrypts files and demands a ransom. However, NotPetya is considered to be more dangerous because it is designed to spread quickly and encrypts not only user files but also the computer’s entire hard drive.
3. Zeus

How do computer viruses work?
Most people have heard about computer viruses, but few know how they work. A virus is a program that copies itself onto other computers, and can cause damage to files or programs. Viruses can spread quickly and easily, and can be hard to get rid of.
There are many different types of computer viruses, but they all work in similar ways. When a virus is first created, it is usually injected into a legitimate program or file. This is known as the “infection vector”. Once the virus is in a program or file, it will wait until the program is run or the file is opened. When the program is run or the file is opened, the virus will activate and begin to copy itself onto other programs or files. This can happen in a number of ways, depending on the virus. Some viruses will simply copy themselves onto any program or file they can find. Others will only infect files that are passed on to others, such as email attachments.
Once a virus has infected a computer, it can start to cause damage. Some viruses will delete files or programs, while others will change the way the computer works. Some viruses can even steal personal information, such as passwords or credit card numbers.
Viruses can spread quickly and easily. When a virus infects a program or file, it usually doesn’t do any damage right away. This means that the virus can sit on a computer for a long time before it is detected. In some cases, a virus can spread to thousands of computers before it is finally noticed and removed.
Most viruses are created by people who want to cause harm to others. However, there are also “accidental” viruses, which are created by people who don’t realize they are creating a virus. For example, a programmer might create a virus while working on a new program. If the programmer doesn’t test the program properly, the virus could be released accidentally.
Viruses can be hard to get rid of. Once a virus has infected a computer, it can be difficult to remove. In some cases, the only way to get rid of a virus is to reinstall the operating system. This means that all of the programs and files on the computer will be deleted, and the computer will have to start from scratch.
There are a few things you can do to protect your computer from viruses. First, you should install antivirus software. This software will scan your computer for viruses and remove them if they are found. You should also be careful about what you download and open. Don’t open email attachments from people you don’t know, and be careful about downloading programs from the internet.
