Are there undetectable viruses
Malware can take many forms, including viruses, worms, trojan horses, ransomware, and spyware. Can malware be undetected Yes, malware can hide itself and antivirus and other protection programs may not catch it. Check out this undetected malware map.
What is the most notorious computer virus
Mydoom
Mydoom. Considered by many to be the most dangerous computer virus in history, the Mydoom virus cost around $38 billion worth of damage in 2004. If you think in terms of today's economy, given inflation, that would amount to about $52 billion. It worked by scraping email addresses from infected machines.
Why is a polymorphic virus difficult to detect
Polymorphic viruses — or any type of malware that contains polymorphic techniques — can be difficult to detect by traditional threat detection methods because of their advanced mutation capabilities.

What is a virus that Cannot be detected
A stealth virus is a computer virus that uses various mechanisms to avoid detection by antivirus software. It takes its name from the term stealth, which describes an approach to doing something while avoiding notice.
What viruses no longer exist
| Disease | Burden of disease | Cause |
|---|---|---|
| Smallpox | Declared eradicated in 1980 | Variola virus |
| Rinderpest | Declared eradicated in 2011 | Rinderpest virus |
| Poliomielitis | 116 cases in 2023 | Poliovirus |
| Guinea worm disease | 30 cases in 2023 | Parasitic worm Dracunculus medinensis |
What is Zeus virus
What is Zeus Virus Zeus Virus (or Zeus Trojan malware) is a form of malicious software that targets Microsoft Windows and is often used to steal financial data.
What is the 1 PC virus
(c)Brain
The first IBM PC compatible virus in the "wild" was a boot sector virus dubbed (c)Brain, created in 1986 and was released in 1987 by Amjad Farooq Alvi and Basit Farooq Alvi in Lahore, Pakistan, reportedly to deter unauthorized copying of the software they had written.
Which type of virus is difficult to detect by scanning because each copy of the virus looks different from the previous copies
Polymorphic viruses are complex file infectors that can create modified versions of itself to avoid detection yet retain the same basic routines after every infection.
Why are boot sector virus hard to detect
It's often hard to detect a boot sector virus infection immediately because the boot sector controls most of the basic booting process. If your computer gets infected and you try to remove the boot virus infection using an antivirus, it may regain access to your computer during the next startup.
What virus no longer exist
So far, only two diseases have been successfully eradicated—one specifically affecting humans (smallpox) and one affecting cattle (rinderpest).
What are examples of hidden viruses
The virus that causes cold sores is an example of a hidden virus. It can remain inactive for months or years inside nerve cells in the face. While hidden, the virus causes no symptoms.
What was the oldest virus
Pandoravirus
And the oldest – a Pandoravirus – was around 48,500 years old. This is the oldest virus ever to have been revived. As the world continues to warm, the thawing permafrost is releasing organic matter that has been frozen for millennia, including bacteria and viruses – some that can still reproduce.
What is the largest viruses name
Mimivirus is the largest and most complex virus known.
What did the ILOVEYOU virus do
ILOVEYOU could — and did — destroy all kinds of files including photographs, audio files and documents. Affected users who didn't have backup copies lost them permanently. In March 1999, similar to ILOVEYOU, the Melissa virus also replicated itself by using Outlook address books.
Is Zeus virus still alive
Like many forms of malware the Zbot was initially used to steal banking information. However, in 2011, the source code was released to the public, allowing multiple new variants to be created. The original code has apparently been retired, but new generations of Zeus trojans are still active today.
Is the first PC virus called the brain
The Brain Boot Sector Virus
Brain, the first PC virus, began infecting 5.2" floppy disks in 1986. As Securelist reports, it was the work of two brothers, Basit and Amjad Farooq Alvi, who ran a computer store in Pakistan.
Does PC virus still exist
No matter which device you use, computer viruses are not a thing of the past. Keep reading to learn more about what a computer virus is and why you should still be concerned about online security in the modern tech age.
Which type of virus is hard to detect as it changes its own code to avoid matching a virus signature
Metamorphic malware completely rewrites every part of its code so that each newly propagated version no longer matches its previous iteration. Such constant and continuous changes make it harder to detect and identify this type of malware.
Which type of virus is hard to detect as it changes its own code to evade matching a virus signature
Thus, stealth-polymorphic viruses are more difficult to detect.
Which virus try to avoid detection
A stealth virus is a computer virus that uses various mechanisms to avoid detection by antivirus software.
Which virus overtake computer system when it boots
A stealth virus is a hidden computer virus that attacks operating system processes and averts typical anti-virus or anti-malware scans. Stealth viruses hide in files, partitions and boot sectors and are adept at deliberately avoiding detection.
What is the oldest virus in the world
Pandoravirus
The youngest virus to be revived was a sprightly 27,000 years old. And the oldest – a Pandoravirus – was around 48,500 years old. This is the oldest virus ever to have been revived.
What is the oldest virus
Nudiviruses, which primarily affects insects and marine arthropods, date back to about 310 million years ago, making it the oldest known virus in the world.
Which virus hides itself
stealth virus
A stealth virus is complex malware that hides itself after infecting a computer.
What old viruses no longer exist
So far, the world has eradicated two diseases — smallpox and rinderpest.
