The Love Bug Virus - Case Study Example A number of security threats such as viruses and worm programs cost business organizations, individuals and government agencies millions of dollars every year. Both the computer viruses and worms belong to a category of software called malware. In this scenario, a Malware or malicious code (malcode) refers to malicious software. In addition, it is a piece of code or software that is purposely developed or written to harm, break, interrupt, steal, or on the whole mete out some other â€Å"terrible† or unlawful act on data, information, hosts, or networks. Additionally, a computer virus is a kind of malware that can vary in harshness and damaging a system from causing slightly disturbing effects to destructing software programs or data and resulting denial-of-service (DoS) attacks. Normally, the majority of computer viruses are incorporated in an executable file, which shows that the virus can stay on a computer or machine however it may not be lively or able to extend until a u ser executes or runs the malicious host program or file. In this scenario, once the system user executes this host code, the infected file or code is also executed along with the program. In fact, the host program works properly even after it is harmed by the virus. On the other hand, a few types of viruses replicate other programs with copies of themselves, which eliminate the infected program and files all in all. Moreover, a virus can enter into a system and extend to other systems when software are connected to is distributed from one machine to another by making use of a USB drive, the network, file sharing, a disk, or infected e-mail attachments (IT Training & Education, 2009; Cisco, 2013; Neubauer & Harris, 2002; Singh & Lakhotia, 2002; Denning, 1990). On the other hand, computer worms are like viruses for the reason that they duplicate practical copies of themselves and can result in the same type of harm.

Rabies - Research Paper Example Different health organizations define rabies according to their respective perspectives. The Centers for Disease and Control Prevention (CDCP, 2010) define rabies as a â€Å"preventable viral disease of mammals most often transmitted through the bite of a rabid animal† (par. 1). The World Health Organization (WHO, 2010) states its meaning as â€Å"a zoonotic disease (a disease that is transmitted to humans from animals) that is caused by a virus† (par. 1). While the Mayo Clinic (Mayo Foundation, 2010) avers that â€Å"rabies is a deadly virus spread to people from the saliva of infected animals. The rabies virus is usually transmitted through a bite† (par. 1). Integrating these definitions, rabies is found to be a deadly but preventable disease caused by a virus transmitted to humans through the saliva of infected animals. The animals clearly identified to contain the dreaded virus range from raccoons, bats, skunks, foxes, cats and dogs, among others. As indicated in the definition, rabies is caused by a virus (of the genus Lyssavirus and family Rhabdoviridae) contracted through a bite from an infected animal. According to Fisher (2008, par. 9), â€Å"when the rabies virus enters muscles, it replicates locally and is then transported through peripheral sensory nerves to the spinal ganglia, where it replicates and travels up the spinal cord to the brain. The virus migrates to the gray matter of the brain and predominates in the neurons of the limbic system, midbrain, and hypothalamus. Efferent nerves transport virus to the acinar glands of the submaxillary salivary glands, where it achieves high concentration†. People who live in rural areas are most at risk in contracting rabies. Children, most especially, those who play in the streets are at a higher risk of being bitten by stray dogs. Further, medical practitioners, such as veterinarians and wildlife researchers or specialists, need to be vaccinated to
