What are the characteristic of virus?
A virus is non-cellular with a typical size of 20-30 nanometers. They contain no cytoplasm or organelles. They have no chromosomes only, RNA and DNA. They have a protein coat. They depend on cells from a host plant or animal for metabolism and reproduction since they are not living organisms.
What does a virus cell look like?
Viruses are not cells and are not made of cells: they are small entities that reproduce inside of cells.
Viruses have many different shapes and forms. They tend to resemble spirals, spheres, and various types of three-dimensional polygons.
The internal structure of a virus is a strand of RNA surrounded by a protein shell.
What was the origin of the Marburg virus?
The Marburg virus is thought to originate from fruit bats, which serve as natural reservoir hosts. Humans can contract the virus through direct contact with infected bats or their bodily fluids. It was first identified in 1967 when outbreaks occurred simultaneously in Marburg and Frankfurt, Germany.
Shedding virus refers to the process in which a person or animal releases virus particles from their body, usually through respiratory secretions or bodily fluids. This shedding can occur even if the individual does not show symptoms of illness, making them capable of spreading the virus to others unknowingly.
What are the two phases of virus activity?
The two phases of virus activity are the infection and the attack phases. The infection phase is when the virus decides to start spreading. The attack phase is when the virus starts causing damage to your computer.
The cell infected by a virus is referred to as the?
The cell infected by a virus is referred to as the host cell. The virus hijacks the host cell's machinery to replicate and produce more virus particles.
Viruses cannot be killed in the traditional sense like bacteria, as they are not considered living organisms. However, they can be effectively neutralized and destroyed through methods such as proper hand hygiene, disinfecting surfaces, and through antiviral medications or vaccines designed to target specific viruses.
What directly attacks host cells that contain bacteria or viruses?
The immune system's T cells directly attack host cells that have been infected by bacteria or viruses. T cells identify these infected cells through the presence of foreign antigens and use various mechanisms to destroy them, such as releasing toxic chemicals or inducing programmed cell death. This process helps to limit the spread of the infection within the body.
What do viruses need to reporduce?
Viruses need a host cell to reproduce. Once they have infected a host cell, they use the cell’s machinery to make copies of themselves. This process eventually leads to the host cell bursting open and releasing new viruses to infect other cells.
What fights viruses by slowing or stopping their multiplication?
interferon.
Keep in mind this drug is a 'last-resort' drug. This drug has been said to have TERRIBLE side-effects. These are real stories
A man once said he had extreme hysteria and shot the family dog because those were one of the side-effects.
Although many people react differently to interferon, one definitely should not risk the outcomes. Some have been recorded to have their hair falling out in only a month! Many people have committed suicide during the use of this drug and have said, "I would rather have hepatitis (the disease this drug is known to cure) than I would have ever used interferon."
True Stories...
Again this is a LAST-RESORT and is extremely RISKY!!
Better Solutions for serious viral diseases such as hepatitis
would be to use MILK THISTLE. This is extra helpful for liver/kidney related diseases.
There are pills that are full of enzymes to help fight against viruses also (drink a lot of these since they are not harmful)
MINOR ILLNESSES:
These are normally simple
1)Drink liquids
2)Buy virus-fighting medicine
3)Don't get a flu shot if you're over the age of 8 or 9 because many of those shots are out of date and only help the drug companies with money because most of those shots are normally out of date and won't work against the ever-changing viruses.
It is a virus effecting whole PC. especial LAN and Software you installed.Internet speed goes down and your installed software may not work as usually.Removing this virus without pro security software is a difficult task.Even though search for some sality removal tool.
Win32/Sality is a family of polymorphic file infectors that target Windows executable files with the extensions .SCR or .EXE. They may execute a damaging payload that deletes files with certain extensions and terminates security-related processes and services.
remedy=to remove it free avast antivirus is a good program download free avast antivirus,install it and run a complete system reboot scan...it will be deleted..
Steps of a virus when a attacking a cell?
How do capsomeres help in viruses?
Answer by Techsupport
capsid provides the second major criterion for the classification of viruses. The capsid surrounds the virus and is composed of a finite number of protein subunits known as capsomeres, which usually associate with, or are found close to, the virion nucleic acid.
What is the difference between a file virus a system sector virus and a macro virus?
File Viruses infect applications. These viruses usually infect COM and/or EXE programs, though some can infect any program for which execution or interpretation is requested, such as SYS, OVL, OBJ, PRG, MNU and BAT files. System Sector Viruses infect executable code found in certain system areas on a disk. Macro Virus a program or code segment written in the internal macro language of an application and attached to a document file (such as Word or Excel).
What do viruses have to rely on for replication?
They rely on their host. They can not reproduce on their own, so they are not considered living. They inject genetic information into a host cell and make the cell produce more viruses.
Why is an error in a computer program called a bug?
The term "bug" to refer to errors in a computer program originated in the early days of computing. In one instance, a moth caused a malfunction in a Harvard Mark II computer in 1947, and engineers found and removed the moth, starting the use of the term "bug" for programming errors.
How are copies of viruses produced?
Viruses replicate by taking over a host cell's machinery to create copies of themselves. This process involves the virus injecting its genetic material into the host cell, which then uses the viral instructions to produce new viral particles. These new viruses can then go on to infect other cells and continue the replication cycle.
How does a hidden virus multiply?
A hidden virus multiplies by hijacking the host cell's machinery to replicate its genetic material and produce new viral particles. The virus then releases these new particles, which can go on to infect other cells and continue the replication cycle.
Viruses are called viruses because, like real-world viruses (e.g., influenza and so on), they 'infect' a computer and often spread throughout it by making copies of themselves and making their code part of other programs. Viruses don't usually spread from computer to computer on their own, instead relying on users to pass on infected files or copies of the virus to other users, such as by email.
What classification is a virus in?
Since this is in the computer virus category, I'll assume that you're referring to a computer virus.
For a computer program to be a virus it must be:
A virus would be classified under the more general category of "Malware", alongside Trojan horses, worms, etc.
See:
http://en.wikipedia.org/wiki/Computer_virus
Otherwise "classification" is highly ambiguous, could you please qualify it?
How are Computer Viruses Developed?
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.
What are the phases of computer virus life cycle?
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.
What is the lifecycle of a computer virus?
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!
How does the macro virus work?
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.
