Computer Viruses

A polymorphic virus is able to change its code to evade detection by antivirus software, making it difficult to analyze and detect.

1981- The "Elk Cloner" for the Apple II Systems was created by Richard Skrenta. It infected the Apple DOS 3.3 and spread to other computers by floppy disk transfer. The "Elk Virus" was responsible for being the first computer virus to cause a massive outbreak ever in history.

pcDNA3 is a plasmid vector commonly used to generate high levels of transient protein expression in mammalian cells, while adeno-associated virus (AAV) is a small, non-pathogenic virus that is commonly used as a vector for gene therapy due to its ability to efficiently transduce a variety of cell types and its low immunogenicity. AAV is typically used for stable, long-term gene expression, while pcDNA3 is mainly used for transient expression.

Viruses were discovered recently because they are microscopic and cannot be seen under a regular microscope. The invention of the electron microscope in the 20th century allowed scientists to visualize and study viruses, leading to their discovery.

The Melissa virus was created in 1999 by David L. Smith. It spread rapidly through email attachments and caused widespread disruption for businesses and individuals. Smith was eventually arrested and sentenced to jail for his actions.

i am not sure who but he was in a college

and he invented a virus called ellic Coner

which was put into a game

Viruses are difficult to cure because they invade host cells to replicate, making it challenging to target them without harming the host cells. Additionally, viruses can mutate quickly, leading to the development of resistance against treatments. This complexity makes it challenging to develop a universal cure for all viruses.

The most common threat posed by an invading virus to a host organism is the potential for the virus to hijack the host's cellular machinery to replicate itself, leading to the destruction of host cells and tissues. This can result in various symptoms of infection and overactivation of the host's immune response, which can cause further damage to the host organism.

Viral load is the term used to describe the number of virus particles circulating in an infected person. It is an important measure of virus replication and infectivity. Tracking viral load levels can help in monitoring disease progression and response to treatment.

A virus forms when its genetic material (RNA or DNA) replicates inside the host cell, using the host cell's machinery to create new virus particles. These new virus particles then exit the host cell to infect other cells and continue the infection cycle.

While viruses exhibit some characteristics of living organisms, such as evolving and reproducing, they lack key features of life, such as the ability to carry out metabolic processes and respond to their environment. Therefore, they are often considered as biological entities that blur the line between living and non-living.

To remove the Sality virus from your PC, you can use reputable antivirus software to scan and remove the infected files. Make sure to keep your antivirus definitions updated to effectively detect the virus. Additionally, you can use malware removal tools such as Malwarebytes to help eliminate any traces of the virus on your system.

It's typically impossible to remove a virus from your DNA because viruses integrate into the host cell's DNA, becoming a permanent part of the genome. Removing a virus would require altering the DNA sequence of every affected cell, which is not currently feasible with existing technology.

Coronaviruses are a group of related viruses that cause diseases in mammals and birds. In humans, they can cause respiratory infections ranging from the common cold to more severe diseases like SARS and COVID-19.

Trichomoniasis is caused by the parasite Trichomonas vaginalis, not a virus. Both males and females can get infected with trichomoniasis, however, males are often asymptomatic carriers of the parasite. It is important for both partners to get tested and treated to prevent transmission.

Viruses do not have a gender. They are microscopic infectious agents that replicate inside living cells.

1.You access the infected website.

2. You download software from a bad website.

3. You get an email that has a itachment that contains a virus.

4.You copy files to your computer from the other Computer that has virus.

Worms replicate themselves by creating copies of their code in files or computer systems. They use various methods to spread, such as exploiting vulnerabilities in software or tricking users into running infected files. Once activated, the worm can self-replicate and spread to other computers on a network.

A virus is a tiny infectious agent that can replicate only inside the living cells of organisms. It typically consists of genetic material surrounded by a protein coat and is capable of causing a variety of diseases in animals, plants, and even bacteria.

they inject a milder form of the disease , so your body won't be fully affected but will remember how to kill the real disease and its weakness

Note, though, that computer viruses are not prevented using vaccines.

Tobacco mosaic virus (TMV) is an RNA virus that infects plants, especially tobacco and other members of the family Solanaceae. The infection causes characteristic patterns (mottling and discoloration) on the leaves (hence the name). TMV was the first virus to be discovered. Although it was known from the late 19th century that an infectious disease was damaging tobacco crops, it was not until 1930 that the infectious agent was determined to be a virus.

Please improve this answer if you know exactly how he discovered this virus.

A virus typically consists of genetic material (DNA or RNA) enclosed in a protein coat called a capsid. Some viruses also have an outer lipid envelope derived from the host cell membrane. Additionally, viruses may have specialized structures like spikes or tails that help them infect host cells.

Metachromatic leukodystrophy is a rare genetic disorder that affects the central nervous system, leading to the breakdown of myelin. Symptoms may include muscle weakness, cognitive decline, and vision and hearing loss. Without treatment, it can result in severe disability and premature death.
