What is the most deadly computer virus ever?
ever

There is no definitive answer to this question as the most deadly virus ever is likely yet to be discovered. However, some of the most deadly viruses discovered to date include the following:

Melissa: This virus was discovered in 1999 and quickly spread through email attachments. It caused major disruptions to email systems around the world and was responsible for an estimated $80 million in damages.

ILOVEYOU: This virus was discovered in 2000 and also spread through email attachments. It affected millions of computers and caused an estimated $10 billion in damages.

MyDoom: This virus was discovered in 2004 and spread through email attachments and file sharing networks. It caused major disruptions to email and Internet services around the world and was responsible for an estimated $52 billion in damages.

Sobig: This virus was discovered in 2003 and spread through email attachments. It caused major disruptions to email systems around the world and was responsible for an estimated $37 billion in damages.

Conficker: This virus was discovered in 2008 and spread through infected USB drives and network shares. It affected millions of computers and caused an estimated $9 billion in damages.

While there is no definitive answer to this question, the viruses listed above are some of the most deadly that have been discovered to date.

What is the most common type of computer virus?

Most people think of computer viruses as harmful code that’s inserted into computer systems in order to cause damage, steal data, or give hackers access to the system. However, not all computer viruses are created equal. Some are more harmful than others, and some are more common than others. So, what is the most common type of computer virus?

According to a report from Kaspersky Lab, the most common type of computer virus is a Trojan horse. Trojan horses are named after the Trojan War in Greek mythology, in which the Greeks used a large wooden horse to sneak soldiers into the city of Troy. In the same way, Trojan horses are used to sneak harmful code into computer systems.

Trojan horses can be used for a variety of malicious purposes, including stealing data, taking control of a system, or delivering damaging payloads. They’re often spread through email attachments or links to malicious websites. Once a Trojan horse is installed on a system, it can be difficult to remove, and it can do a lot of damage.

Interestingly, Kaspersky’s report found that the number of Trojan horses has been declining in recent years. This is likely due to the fact that many people are now using antivirus software that can detect and remove Trojan horses. However, even though the number of Trojan horses is decline, they’re still the most common type of computer virus, so it’s important to be aware of them and take steps to protect your system.

What is the most powerful computer virus in the world?

There is no definitive answer to this question as it largely depends on perspective. However, here are three of the most powerful computer viruses in the world, based on their ability to cause widespread damage, their resilience and their level of sophistication.

1. WannaCry

WannaCry is perhaps the most well-known and feared computer virus in the world. It first made headlines in May 2017 when it caused a global ransomwareattack, infecting more than 230,000 computers in 150 countries and causing billions of dollars in damage.

What made WannaCry so powerful was its use of a then-undetected flaw in Microsoft Windows known as the EternalBlue exploit. This allowed the virus to spread rapidly and indiscriminately across networks, encrypting files and demanding ransom payments in order to decrypt them.

Fortunately, a security researcher known as MalwareTech accidental discovered a kill switch that halted the spread of WannaCry. However, the success of WannaCry served as a wake-up call for the need for improved cyber security, and similar ransomware attacks have since been carried out with varying degrees of success.

2. Stuxnet

Stuxnet is widely considered to be the most sophisticated computer virus ever created. It is believed to have been developed jointly by the US and Israeli governments for the purpose of sabotaging Iran’s nuclear program.

Stuxnet was designed to specifically target industrial control systems, and it is estimated to have caused extensive damage to Iran’s nuclear facilities. In addition to physical damage, Stuxnet also caused major disruptions to Iran’s nuclear program and set it back years.

While Stuxnet was successful in its mission, it is also considered to be one of the most dangerous computer viruses in the world. This is because the same sophistication that allowed it to successfully target Iranian nuclear facilities could also be used to target critical infrastructure in other countries.

3. Zeus

Zeus is a sophisticated malware that has been used to carry out a wide range of cybercrime, including stealing login credentials, personal information and financial data.

What makes Zeus particularly powerful is its ability to evade detection and to spread quickly and easily. It is estimated that Zeus has infected millions of computers around the world and has caused hundreds of millions of dollars in damage.

While Zeus is primarily used for financial gain, it also has the potential to be used for more malicious purposes such as identity theft, data breaches and even sabotage.

These are just three of the most powerful computer viruses in the world. However, it is important to remember that any computer virus has the potential to cause serious damage, and even the most sophisticated viruses can be stopped with the right precautions in place.

What was the first computer virus?

The first computer virus was the work of a German programmer in the early 1980s. The virus, which he called the “Elk Cloner,” was designed to infect Apple II computers. When a user ran a program infected with the virus, the virus would copy itself to the user’s floppy disk. The virus would then infect any other computers that used that floppy disk.

The Elk Cloner was not a destructive virus, but it did cause a lot of headaches for Apple II users. The virus quickly spread, and soon there were reports of infected computers all over the world.

In the 1990s, a new type of computer virus began to spread: the “Trojan Horse.” Unlike the Elk Cloner, which just caused annoyance, Trojan Horses could be used to damage or destroy a computer.

One of the most famous Trojan Horses was the “Melissa” virus, which was released in 1999. Melissa spread quickly, infecting over one million computers in just a few weeks. The damage caused by Melissa was estimated to be over $80 million.

Today, there are still many computer viruses circulating on the Internet. While most of them are not as damaging as Melissa, they can still cause a lot of problems for users.

How do computer viruses spread?

Most deadly computer viruses

A computer virus is a type of malicious software that, when executed, replicates itself by modifying other computer programs and inserting its own code. When this replication succeeds, the affected areas are said to be “infected” with a virus.

Viruses often spread by creating a copy of themselves on a network file system or hard drive. From there, they can infect other executable files and documents. Virus creators often exploit security vulnerabilities to spread their creations.

In general, there are three ways that a computer virus can spread:

Via removable media: This is the most common method of virus propagation. A virus infects a system when the user executes infected programs or documents from removable media such as USB drives, CDs, or DVDs.

Via email and instant messaging: Email messages and attachments are common sources of virus infection. The email may contain an infected attachment that, when opened, launches the virus. Alternatively, the email message may contain a link to an infected website. When the user clicks the link, the virus is downloaded and executed.

Via network file sharing: Network file sharing is a common vector for virus propagation. When a user executes an infected program from a network share, the virus spreads to the user’s system. The virus can also spread by infecting files on the network server.
