The most dangerous PC viruses of 2019

The year 2019 has seen its fair share of devastating viruses and malware attacks. From the WannaCry ransomware attack that hit businesses and organizations around the world, to the NotPetya attack that crippled Ukraine’s critical infrastructure, these viruses have caused immense damage and disruption.

While there have been many scary viruses and malware attacks this year, there are a few that stand out as the most dangerous. Here are the most dangerous PC viruses of 2019.

1. WannaCry

The WannaCry ransomware attack was one of the biggest and most widespread malware attacks of 2017. It affected over 200,000 computers in 150 countries and caused billions of dollars in damage. The virus encrypted files on infected computers and demanded a ransom of $300 in Bitcoin to decrypt them.

While WannaCry was mostly shut down and contained within a few days, it still caused a lot of damage. Many businesses and organizations were forced to shut down their computers and systems until they could remove the virus. The WannaCry attack was a wake-up call for many businesses and organizations about the importance of cybersecurity.

2. NotPetya

The NotPetya virus was first discovered in June 2017. It initially spread through Ukraine before quickly spreading to other countries. NotPetya is a ransomware virus that encrypts files on infected computers and demands a ransom for decrypting them.

However, unlike other ransomware viruses, NotPetya does not seem to have a way to decrypt the files even if the ransom is paid. This makes it much more destructive and dangerous. NotPetya also has a destructive “wiper” function that can delete critical system files, making it even more damaging.

NotPetya caused billions of dollars in damage and was one of the most destructive viruses of 2017. It crippled Ukraine’s critical infrastructure, including its power grid, banks, and government agencies. The virus also spread to other countries, causing damage to businesses and organizations around the world.
