Computer virus

reactivate and the virus starts transcribing its genes again. It is important to state that once a person has been infected with Herpes Simplex Virus, this virus will remain latent in the hosts body for years and will eventually reactivate periodically causing the disease. Different stimuli can cause the virus to leave its dormant state such as, fever, trauma, emotional stress, sunlight, and menstruation. Herpes Simplex Virus can be transmitted into the host body through direct contact between…

The study of influenza virus evolution is not new. In fact, humans have been studying influenza viruses since the beginning of the 18th century. Three types of influenza viruses exist: A, B and C. Influenza B is a strain of influenza virus with the ability to cause severe epidemics. Although influenza A and B have similar structure, genome organization, and epidemiology, they have several important differences which imply that their evolutionary dynamics differ. Unlike influenza A viruses,…

A virus- a complex microscopic organism that possesses the ability to replicate inside the cells of a host. For centuries scientists have debated the topic of whether viruses are living organisms- or not. Viruses have been left in a “gray area”, becoming ignored in the study of evolution by scientists. When not in contact with a host, viruses tend to stray from the characteristics that define life. Characteristics such as the ability to respond to their environment, lack of cells, and the…

Mononucleosis also known as the kissing disease is caused by an infection with the epstein-barr virus. Also caused by being exposed to someone who has this disease. This disease is actually very common and isn't permanent. If you have this disease you need to be cautious because you are contagious. There are many symptoms to this disease such as, fever, rash, swollen glands, sore throat, headache, soft swollen spleen, swollen tonsils, fatigue, swollen lymph nodes (on the neck and armpits), and…

personal information in computer and mobile devices. For business, McAfee provides the security in web server, emails, and networks; it also prevents the data loss in computer and in cloud server. There are many different ways that McAfee antivirus uses to detect harmful threats in personal devices like signature based, heuristic based, behavioral based, and sandbox detection. In signature based, McAfee antivirus will check all the EXE file and unknown running file for any sign of virus. It…

The danger for the average computer user is that someone will hack their system. Most average computer users don’t have anything worth stealing. Now, on the internet, there are other dangers, because your computer could be a launching pad for other attacks. So people might want to break into your computer in order to use it later on as a tool to break into something bigger. These things happen all the time. A lot of DoS (Denial of Service) attacks are based off these types of intrusions. A DoS…

Gene Therapy and Genetic Engineering in Human Beings We, as human beings, all start off the same way. A lucky sperm meets an egg and forms the beginning of a whole new life. From that very moment it is predetermined in our DNA that we will have a certain color of hair, be of a certain height, and what color that our eyes will be. Then, approximately nine months later we are welcomed into the world carrying with us every trait that our DNA tells us to have. People will come in to see the miracle…

There are many ways of getting sick such as airborne, touching someone. For a long time this is how people have gotten a cold or chicken pox. As medicine is readily available to aid in the recovery of an illness. Viruses can become resistant to medicine just as our bodies could resist to some sicknesses. In the book Biological Terrorism by Steve Goodwin and Randall W. Phillis they present a history of microorganism used to help cure diseases and misused by Medics, and biological warfare. To…

At Mayo Clinic we have more than 4,000 world class physicians in every medical specialty dedicated to working together to chart the quickest path to healing. When it comes to cancer research, Mayo Clinic has the broadest, most comprehensive oncolytic virotherapy program in the US. Thanks to benefactors, Mayo Clinic Cancer Center (MCCC) is making great…

the origin of the CRISRP acronym. These CRISPR sequences are specific patterns of DNA sequences that are capable of being edited out of genes. Using the CRISPR system, bacteria are able to destroy the genome of invading viruses and thus prevent the virus from being able to replicate and survive in its host.…
