rojan:SymbOS/Locknut

Trojan:SymbOS/Locknut.A is a malicous SIS file trojan that pretends to be patch for Symbian Series 60 mobile phones. It is distributed in files named patch_v1.sis and patch_v2.sis.

Locknut.A will only work on devices running Symbian OS 7.0S or newer; devices using Symbian OS 6.0 or 6.1 are unaffected.

Locknut is targeted against Symbian Series 60 devices, but also series 70 devices, such as Nokia 7710 are vulnerable to Locknut. However when trying to install Skulls trojan on Nokia 7710, user will get a warning that the SIS file is not intended for the device, so risk of accidental infection is low.

Installation

When Locknut.A sis file is installed the files will be installed into following locations: Continue reading

Parvovirus B19 Infections

Parvovirus B19 Infections
Parvovirus B19 Infections

Infections caused by human parvovirus B19 can result in a wide spectrum of manifestations, which are usually influenced by the patient’s immunologic and hematologic status. In the normal host, parvovirus infection can be asymptomatic or can result in erythema infectiosum or arthropathy. Patients with underlying hematologic and immunologic disorders who become infected with this virus are at risk for aplastic anemia. Hydrops fetalis and fetal death are complications of intrauterine parvovirus B19 infection. (Am Fam Physician 1999;60:1455-60.)

Parvovirus B19 was discovered fortuitously in 1975 by Cossart and colleagues,1 who unexpectedly found viral particles in the sera of asymptomatic patients being screened for hepatitis B infection. Biochemical and molecular characteristics subsequently demonstrated that these particles were parvoviruses and, because specimen 19 of panel B contained the unexpected virus, parvovirus B19 was so designated.

What is HPV?

There are over a hundred viruses known as human papilloma virus (human papilloma virus / HPV). They are common. One study found HPV in 77% of HIV-positive women. HPV is transmitted easily through sexual intercourse. An estimated 50% of sexually active people aged 15-49 years in the U.S. had at least one type of HPV infection. Statistics for Indonesia is not yet known.

Various types of HPV cause warts, usually on the hands or feet. Infections of the hands and feet are usually not transmitted through sexual activity. Some types of HPV can cause genital warts on the penis, vagina and rectum. HIV can get worse sores in the rectum and cervical area. HPV can also cause problems in the mouth or on tongue and lips. Other HPV types can cause abnormal cell growth known as dysplasia. Dysplasia can develop into anal cancer in men and women, and cervical cancer (cervical cancer), or cancer of the penis Continue reading

Hepatitis B – Transmission And Treatment

Hepatitis-Liver-Hepatitis-Virus
Hepatitis-Liver-Hepatitis-Virus

Hepatitis B Hepatitis B is a liver disease caused by hepatitis B virus (HBV), a member of Hepadnavirus which can cause acute or chronic inflammation of the liver are in a minority of cases may progress to liver or liver cancer sirosi. Treatment of hepatitis B progressively developed by the various State and become one of the World Health Organization’s attention.

The cause of hepatitis was not merely a virus. Drug toxicity, and exposure to various chemicals such as carbon tetrachloride, chlorpromazine, chloroform, arsenic, phosphorus, and other substances used as medicine in the modern industry, can also cause hepatitis. These chemical substances may be ingested, inhaled or absorbed through the skin of the patient. Neutralize toxins circulating in the blood is the work of the heart. If a lot of toxic chemicals that enter the body, the liver can be damaged so that it can no longer neutralize the other toxins. Continue reading

Viruses Genomes – Human Adenovirus

Adenovirus_New
Adenovirus_New

Adenoviruses are medium-sized (90–100 nm), nonenveloped (naked) icosahedral viruses composed of a nucleocapsid (protein shell) and a double-stranded linear DNA genome. Viruses of the family Adenoviridae infect various species of vertebrates, including humans. Adenoviruses were first isolated in human adenoids, from which the name is derived.

Adenoviruses were first discovered in 1953. Since then, over 50 different serotypes of Human adenoviruses have been isolated and characterized, and the family Adenoviridae has been shown to be comprised of numerous non-human serotypes from a variety of mammalian, avian, reptilian, amphibian, and even fish species.

In humans, there are 49 accepted Human adenovirus types (1-49) in twelve species (H. adenovirus A to G), and about half of those are believe to cause human disease: Continue reading

Reoviridae Is a Family Of Viruses That Can Affect The Gastrointestinal System

Reoviridae
Reoviridae

Reoviridae is a family of viruses that can affect the gastrointestinal system (such as Rotavirus) and respiratory tract. Viruses in the family Reoviridae have genomes consisting of segmented, double-stranded RNA (dsRNA).[1] The name “Reoviridae” is derived from respiratory enteric orphan viruses. The term “orphan virus” means that a virus that is not associated with any known disease. Even though viruses in the Reoviridae family have more recently been identified with various diseases, the original name is still used.

Reovirus infection occurs often in humans, but most cases are mild or subclinical. The virus can be readily detected in feces, and may also be recovered from pharyngeal or nasal secretions, urine, cerebrospinal fluid, and blood. Despite the ease of finding Reovirus in clinical specimens, their role in human disease or treatment is still uncertain. Continue reading

Pathogenesis of Experimental Vesicular Stomatitis Virus

The pathogenesis of vesicular stomatitis virus (VSV) infection has not been investigated previously in native New World rodents that may have a role in the epidemiology of the disease. In the present study, 45 juvenile and 80 adult deer mice (Peromyscus maniculatus) were inoculated intranasally with VSV New Jersey serotype (VSV-NJ) and examined sequentially over a 7-day period. Virus was detected by means of immunohistochemistry and in situ hybridization in all tissues containing histologic lesions. Viral antigen and mRNA were observed initially in olfactory epithelium neurons, followed by olfactory bulbs and more caudal olfactory pathways in the brain. Virus also was detected throughout the ventricular system in the brain and central canal of the spinal cord. These results support both viral retrograde transneuronal transport and viral spread within the ventricular system. Other tissues containing viral antigen included airway epithelium and macrophages in the lungs, cardiac myocytes, and macrophages in cervical lymph nodes. In a second experiment, 15 adult, 20 juvenile, and 16 nestling deer mice were inoculated intradermally with VSV-NJ. Adults were refractory to infection by this route; however, nestlings and juveniles developed disseminated central nervous system infections. Viral antigen also was detected in cardiac myocytes and lymph node macrophages in these animals. Viremia was detected by virus isolation in 35/72 (49%) intranasally inoculated juvenile and adult mice and in 17/36 (47%) intradermally inoculated nestlings and juveniles from day 1 to day 3 postinoculation. The documentation of viremia in these animals suggests that they may have a role in the epidemiology of vectorborne vesicular stomatitis. Continue reading

Beware, The Ebola Virus Craze

Ebola virus is a virus of the filovirus family Filoviridae genus, and can cause fever hemoroik (ebola hemorrhagic fever) are great in humans. Ebola is a deadly infectious disease. This virus was first discovered in Africa precisely at Zaire, and can attack the monkeys, apes, chimpanzees, and humans in particular.

Until now genetically identified four types of ebola virus, the first Ebola Zaire, where the virus is discovered in Zaire in 1976 that the first outbreak of ebola virus, Ebola Sudan, where the second type was first discovered in the western part of Sudan in late 1976 and tahub strike back at 1979, the three Ebola Reston virus which is a variation of the Ebola virus found in Africa monet imported from America, and the fourth Ebola Ivory Coast who was found in 1995 in Ivory coast West Africa in the Tai forest.
