Viruses can not replicate without a living host cell. This is one reason that they are not considered to be alive.
Sometimes they do and people can die from it.
No, Neither Roblox of Facebook have viruses. People on Facebook do sometimes post links to viruses, and there are scams that exist on Facebook, but there are no viruses on Facebook itself. Roblox does not have viruses either. It does have virus scripts within the game, but those cannot actually harm your computer.
When people sometimes just do it for fun to make people angry and to find out other peoples secrets and to steal other peoples money.
Sometimes, it is. But most of the time, the people who make the programs put viruses on them for fun. So, you always need to check for viruses with an anti-virus.
Because H1N1 influenza viruses are not retroviruses. Therefore, they are treated with antivirals instead of antiretrovirals. They are also from different families of viruses. Influenza viruses, like H1N1, are in the viral family called Orthomyxoviridae. Retroviruses are from the viral family Retroviridae. Retroviruses are very different viruses with different methods of replication and, therefore, require different treatment. The influenza viruses and retroviruses are alike in that they are considered RNA viruses. Some people mistakenly think that the R in RNA stands for retrovirus - it actually stands for Ribonucleic acid. (DNA is Deoxyribonucleic acid). While retroviruses and H1N1 are both RNA viruses (instead of DNA viruses), retroviruses are able to transcribe that RNA into DNA, which is what instructs the cells they infect in the viral replication process. H1N1 does not convert its RNA into DNA. The term "retro" in retrovirus refers to this reversal that makes DNA out of the RNA.
Not sure if you mean to question the virus in biology or in computer software, however I shall answer both questions. In biology viruses are actually used to combat new diseases and create cures. The can actually be used also for technology where a virus was actually used in a battery for-to power a device similar to a computer. In computer software, sometimes people create viruses as almost a hobby. They are they hackers, the thieves, or whatever you want to call them, of the CyberWorld. Viruses can be used to steal information and identities. Viruses have actually been used also to download illegally. The unknown side of viruses is that a good portion of them are actually created accidently. These are most common as boot-sector viruses. However, then can entail other forms as well. Usually they pop up when there are compatibility issues and the computer crashes. - So to answer, sometimes people create viruses for illegal purposes or sometimes they are created by accident.
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
Viruses have the ability to greatly affect life on earth. Many viruses, such as HIV and influenza have killed millions of people. By studying viruses, scientists are able to develop vaccines that will protect people (and animals) from viruses.
Depending on what the virus is designed to do, anything could happen. Usually, viruses will not delete your files - people who write viruses are more interested in stealing your information than destroying it. Sometimes, however, viruses will delete your files or even corrupt your hard drive completely.
People experience strokes because of different reasons. It could originate from a condition in the heart. the person could have a blood disorder which is prone to clotting, which can lead to a stroke. It can be genetic. Sometimes viruses can cause it. Occasionally stress. And sometimes, its just completely random.
Independent People was created in 1934.
Well, hackers usually try to get information that is not theirs to know. Sometimes they plant viruses. If they do it on accident or not, I'm not really sure.
