Computer Viruses

Computer viruses are typically developed by individuals with advanced programming skills who write malicious code to exploit vulnerabilities in computer systems or software. They may use a variety of programming languages and techniques to create the virus, often incorporating stealthy tactics to evade detection by security software. The ultimate goal of virus development is often to gain unauthorized access to a system, steal sensitive information, or disrupt normal computer operations.

The phases of a computer virus life cycle typically include: infection, replication, activation, and spread. During the infection phase, the virus gains entry into a system. In the replication phase, the virus creates copies of itself to spread further. Activation occurs when the virus is triggered to execute its malicious payload. Finally, the virus spreads by infecting other systems through various means.

A computer virus typically starts with the infection phase, where it enters a system. It then replicates itself to spread to other systems, followed by the activation phase when it executes its malicious payload. Finally, the virus may enter a dormancy phase where it remains undetected or gets removed by antivirus software.

Viruses are killed by plain oxygen, above the 20.08% of what we breath. Viruses are Anaerobic, meaning - when it comes in contact with H202, ozone, or just simply a medical bottle of compressed oxygen with a regulator fed anally for just a few Minutes at a time, for HIV!

I've never had the virus myself, but i know alot about it just by reading about it on the internet. surch on google, "Macro Virus", and you will ge tones of grerat answers about the topic... personals i like the site riht off of Microsoft, surch Macro virus, and the fourth link down, is a great place to look.

Phase contrast microscopy is often used for viewing colorless specimens, as it enhances the contrast between different parts of the specimen based on density differences. This type of microscopy is particularly useful for observing live biological samples without the need for staining.

Every virus has two main parts: a protein coat called capsid that surrounds and protects the genetic material, and the genetic material itself which can be DNA or RNA. The genetic material contains the instructions needed for the virus to replicate and infect host cells.

There are different types of viruses. Some of the prominent ones are Trojan horses , worms, and email viruses. The Trojan horses are computer programs which pretend to do one thing but actually do damage when they start it. The worms viruses are pieces of software that use computer networks and security flaws to create copies of itself. A cop y of the worm will then scan the network for any other machine that has a specific security flaw, and then replicate itself to the new machine. With regards to email viruses, these use email messages, and usually will copy and automatically mail itself to hundreds of people.

There are two generalities of viruses, including resident and nonresident viruses. Resident viruses are those viruses that contain a specific replication module which is alarmingly similar to t hose employed by nonresident viruses. A resident virus is one that stays in memory after it executes, and even after its host program is executed. Resident viruses are often subdivided into categories like fast infectors, and slow infectors. Fast infectors are those particular viruses which are designed to affect as many files as possible and slow infectors are designed to infect hosts infrequently. For instance some slow infectors will only infect files when they are copied.

Nonresident viruses on the other hand are those viru ses which consist of a finder module and a replication module. The finder module is responsible for finding new files to infect, while the replication module is the component that actually infects the found files

If you have windows already in your computer then the window that you think is asking to install the windows might be of installing the updates or other functions about it. and if it is only asking to install windows then it is possible that might be virus messages to do not press or anything once run a system scan with an anti virus software.

A worm virus is a type of malware that self-replicates and spreads over computer networks, exploiting vulnerabilities in software to infect other devices. Once a device is infected, the worm can execute malicious actions like stealing data, causing damage, or creating backdoors for further attacks. Worm viruses can spread rapidly, causing widespread damage if not contained quickly.

Viruses are classified based on various characteristics such as their type of genetic material (DNA or RNA), their shape, size, mode of transmission, and the host they infect. They are categorized into families, genera, and species based on these criteria. The International Committee on Taxonomy of Viruses (ICTV) is responsible for officially classifying and naming viruses.

Meristem tissues are virus free because they have a high rate of cell division and low metabolic activity, making them less susceptible to viral infections. Additionally, meristems often lack open plasmodesmata connections that viruses typically use to spread between plant cells. Lastly, meristem cultures are often treated with antiviral agents or heat therapy to eliminate any existing viruses.

No, Ameba Pico is not a virus. It is a legitimate online game that can be played on social platforms like Facebook. However, it is important to ensure that you access the game through official and secure channels to avoid any potential risks.

bcoz some viruses are able to survive even in extreme hard conditions like high temperature. For those medicines r used which breaks the bases of their DNA. REMEMBER..... viruses r prokaryotic and they r from the very beginning of life on earth. they infect the hosts and more viruses r created and .......u know what

For more visit.. http://en.wikipedia.org/wiki/Virus#Bibliography. they also have a protein coating which is hard to break in to.

As with any online game, there is a potential risk of downloading viruses when playing Pokemon volcano if you visit third-party sites or download content from unreliable sources. It is essential to only download the game from official sources and ensure your device has proper antivirus protection to minimize the risk of viruses.

Viruses replicate quickly and mutate frequently during their life cycle, which allows them to adapt rapidly to new environments and hosts. This high mutation rate gives viruses the ability to evolve and potentially jump to a different host species. Additionally, some viruses have broad host ranges due to their ability to bind to receptors that are conserved across different species.

Well it depends. If they keep their worlds clean, then they wouldn't have any sicknesses. But, i think its 100% sure that people often get sick in small worlds because every one has germs and since its a small world, ppl r cluttered together and germs go hand in hand.

viruses are not living things because they only carry out reproduction which is only one of the characteristics of a living thing.

a thing to be called living it should have all the seven characteristics listed below:

Respiration - viruses don't respire(breathe)

Nutrition - viruses do not feed

Excretion - since they don't eat and breathe they don't give out anything

Sensitivity - they are not aware of the surrounding expect for their survival

Growth - viruses don't grow no increase or decreaase in size

Movement - they move

Reproduction- they reproduce

since only two characteristics are present viruses are declared non living .

It would not be advantageous for a virus to kill its host because if the host dies, the virus would also die since it needs the host to replicate and spread. It is more beneficial for a virus to keep the host alive so it can continue to infect other individuals.

Yes, viruses replicate by invading host cells and using their cellular machinery to produce copies of themselves. This replication process can lead to the spread of the virus to other cells or individuals.

Viruses can be as small as 20 nanometers in diameter, which is about 100 times smaller than a typical bacteria cell. They are considered the smallest infectious agents and require an electron microscope to be viewed.

The nucleic acid of a virus is covered by a protein capsid.

In virology, temperate refers to the life cycle some phages are able to perform. Atemperate phage can integrate its genome into its host bacterium's chromosome, becoming a lysogen known as a prophage. A temperate phage is also able to undergo lytic life cycles, where the prophage is expressed, replicates the phage genome and produces phage progeny and the progeny phage leave the bacterium.

The virulent phages have only lytic lifecycles and thus infection results in the host cell's death (due to lytic cell destruction-the phage replicates itself and then bursts the cell, releasing many copies).
