How were computer viruses created
As noted by Discovery, the Creeper program, often regarded as the first virus, was created in 1971 by Bob Thomas of BBN. Creeper was actually designed as a security test to see if a self-replicating program was possible.
What is a computer virus and how is it made
A computer virus is malicious code that replicates by copying itself to another program, computer boot sector or document and changes how a computer works. A virus spreads between systems after some type of human intervention.
What are computer viruses made up of
A computer virus generally contains three parts: the infection mechanism, which finds and infects new files, the payload, which is the malicious code to execute, and the trigger, which determines when to activate the payload. Also called the infection vector, this is how the virus spreads.
Are computer viruses man made
Computer viruses are never naturally occurring; they are always man-made. Once created and released, however, their spread is not directly under human control.
What was the 1st virus
Research on viruses has been recognized with several Nobel Prizes. Viruses attack both animals and plants. Tobacco plants are damaged sometimes with mosaic-like patterns on the leaves. These patterns are caused by the tobacco mosaic virus, which at the end of the 19th century became the first virus ever discovered.
Who created first virus for PC
Amjad Farooq Alvi
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.
Who released first PC virus
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.
Why do people create computer viruses
Causing problems and trouble
Some people create viruses and malware because they enjoy causing trouble and making others suffer. Some malware can crash an entire network system and cause system outages for large companies, like banks or production companies.
How viruses are written
When you are writing a computer virus, you are writing a computer program, which is only possible if you know a programming language. Some of the most popular languages for writing malware are Python, C/C++, Javascript, and PHP.

Do good computer viruses exist
Even a "good" virus uses system resources such as disk space, memory and CPU time. All programs, including viruses, contain bugs that can have unintended and damaging consequences. "Good" viruses are likely to produce many false positives from virus scanners, costing users in the time it takes to respond to the alerts.
Which virus is the smallest virus
Adenovirus is the smallest virus and Mycoplasma is the smallest bacteria. Both bacteria and viruses are contagious organisms that lead to many diseases in both plants and animals.
Does virus have DNA
Chemical Composition and Mode of Replication: The genome of a virus may consist of DNA or RNA, which may be single stranded (ss) or double stranded (ds), linear or circular. The entire genome may occupy either one nucleic acid molecule (monopartite genome) or several nucleic acid segments (multipartite genome).
Why do computer viruses exist
There are three primary reasons why they create them: To make money. To steal account information. To cause problems and trouble for others.
What’s the worst virus
Top 10 most dangerous viruses in the worldMarburg virus. The most dangerous virus is the Marburg virus.Ebola.Hantavirus.Bird flu virus.Lassa virus.Junin virus.The Crimea-Congo fever.The Machupo virus.
What was the first virus
Tobacco mosaic virus
Abstract. Two scientists contributed to the discovery of the first virus, Tobacco mosaic virus. Ivanoski reported in 1892 that extracts from infected leaves were still infectious after filtration through a Chamberland filter-candle.
Is it illegal to make computer viruses
No. It is not against the law or a crime to make a computer virus, Trojan, or malware. However, if that virus spreads to other computers intentionally or by mistake, you've violated the law, and you could be held liable for any damages it causes.
Who writes viruses and why
They're often kids, but not always. In general, virus writers are young people under 30 and predominantly male, Gordon says. Many are in their teens. But stereotypes can be dangerous here, because some veteran IT people have been known to write viruses on the side to “test the security” of certain networks and systems.
Can viruses break your PC
At the same time, the virus is wreaking havoc: it can damage programs, delete files, and make devastating changes to your hard drive, all of which can result in reduced performance. Some viruses will even crash your entire system.
Do computer viruses expire
Does a virus (malware) ever expire Yes, but they are very rare and are highly target-specific when running after a specific date means that the malware might be discovered or have specific effects that the malware writers don't want.
How big is the biggest virus
1.5 microns
The physically largest virus is Pithovirus sibericum, at 1.5 microns (or 1,500 nanometers) in length [2]. Though that might seem tiny, it is larger than some bacteria, and approximately half the width of a strand of spider web silk [3].
Who is the largest virus
Giant Mimivirus
Discovery of the Giant Mimivirus. Mimivirus is the largest and most complex virus known. Is it an evolutionary bridge between nonliving viruses and living organisms, or is it just an anomaly Viruses are small and fairly simple.
Is coronavirus A DNA or RNA virus
Coronaviruses (CoVs) are positive-stranded RNA(+ssRNA) viruses with a crown-like appearance under an electron microscope (coronam is the Latin term for crown) due to the presence of spike glycoproteins on the envelope.
How much of human DNA is virus
Eight percent
Eight percent of our DNA consists of remnants of ancient viruses, and another 40 percent is made up of repetitive strings of genetic letters that is also thought to have a viral origin.
