Can a computer virus copy itself
virus (computer virus) 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 is the difference between a virus and a Trojan horse
A Virus is a malicious executable code attached to another executable file which can be harmless or can modify or delete data. Trojan Horse is a form of malware that captures some important information about a computer system or a computer network.
What was the first computer virus
Brain
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.
What type of malicious software is designed to replicate itself to other computers
Worms
What is a worm Worms are programs that replicate themselves from system to system without the use of a host file.
Which virus copies itself
Worms are a self-replicating type of malware (and a type of virus) that enter networks by exploiting vulnerabilities, moving quickly from one computer to another. Because of this, worms can propagate themselves and spread very quickly – not only locally, but have the potential to disrupt systems worldwide.
Can a virus self-replicate
A Virus is a self-replicating code segment which must be attached to a host executable. When the host is executed, the virus code may also execute. If possible, the virus will replicate by attaching a copy of itself to another executable.
Which virus replicates itself
Worms
Worms are malware that self-replicate & propagate independently once in the system.
Are all Trojans viruses
Is a Trojan a virus or malware Trojans are not viruses, but they are a type of malware. People sometimes refer to “Trojan viruses” or “Trojan horse viruses,” but there's no such thing.
What is the most expensive virus in the world
The Costliest Computer VirusesMydoom. Estimated cost of damage: $38.5 billion. “Mydoom” has such an ominous ring to it, and the virus lived up to its name.Sobig. Estimated cost of damage: $30 billion.Klez. Estimated cost of damage: $20 billion.
What is the most powerful computer virus
the Mydoom virus
1. 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.
Can a computer virus replicate itself True or false
A computer virus is a type of malware that, when executed, replicates itself by modifying other computer programs and inserting its own code into those programs.
Do viruses worms and Trojan horses replicate themselves to other computers or devices
While viruses and worms self-replicate to establish their presence, Trojans do not. Essentially, Trojans are a delivery system. Instead of self-replication, Trojans invade your computer by pretending to be a helpful software program or file.
Do viruses copy their DNA
DNA viruses replicate their genomes using DNA polymerase enzymes and transcribe their mRNA using DNA-dependent RNA polymerase enzymes.
Did 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).
What type of virus copies itself
A computer worm is a type of malware whose primary function is to self-replicate and infect other computers while remaining active on infected systems. A computer worm duplicates itself to spread to uninfected computers.
Can viruses self reproduce
They do not possess ribosomes and cannot independently form proteins from molecules of messenger RNA. Because of these limitations, viruses can replicate only within a living host cell.
Can Trojans be false
There are instances where an executable can be mislabeled as a Trojan. So while a Trojan is definitely a malicious program, there have been instances where legitimate files have been classified as Trojans.
Can Trojan virus be fake
What's worse than a trojan virus Perhaps, a fake trojan virus. Fake trojans appear in the form of a pop-up window, usually in a browser, and claim that your computer has been infected and you need to take urgent action to get rid of it.
Is the ILOVEYOU virus still exist
Although the ILOVEYOU virus is no longer active, it serves as an example of how quickly malicious code can spread across the internet and cause widespread damage. Additionally, it highlights the importance of being aware of cyber threats and taking steps to protect yourself from them.
How much did the ILOVEYOU virus cost
The outbreak was later estimated to have caused US$5.5–8.7 billion in damages worldwide, and estimated to cost US$10–15 billion to remove the worm. Within ten days, over fifty million infections had been reported, and it is estimated that 10% of Internet-connected computers in the world had been affected.

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.
Which computer virus repeat itself
Worms are a self-replicating type of malware (and a type of virus) that enter networks by exploiting vulnerabilities, moving quickly from one computer to another. Because of this, worms can propagate themselves and spread very quickly – not only locally, but have the potential to disrupt systems worldwide.
Can viruses live and replicate on their own
Viruses are not cells: they are not capable of self-replication and are not considered “alive”. Viruses do not have the ability to replicate their own genes, to synthesise all their proteins or to replicate on their own; thus, they need to parasitise the cells of other life-forms to do so.
Can virus and worms replicate themselves
Comparative Analysis of Malware, Virus, and Worm
A worm can replicate and spread itself from one computer to another. On the other hand, a virus cannot self-replicate, and it needs to be sent by a user or software to travel between two different computers.
