A computer virus [1] is a type of malware that, when executed, replicates itself by modifying other computer programs and inserting its own code into those programs. [2] [3] If this replication succeeds, the affected areas are then said to be "infected" with a computer virus, a metaphor derived from biological viruses.
A proof of concept virus has used the Graphics Processing Unit (GPU) to avoid detection from anti-virus software. The potential success of this involves bypassing the CPU in order to make it much harder for security researchers to analyse the inner workings of such malware.
Virus classification. Virus classification is the process of naming viruses and placing them into a taxonomic system similar to the classification systems used for cellular organisms . Viruses are classified by phenotypic characteristics, such as morphology, nucleic acid type, mode of replication, host organisms, and the type of disease they cause.
Virology. Gamma phage, an example of virus particles (visualised by electron microscopy) Virology is the scientific study of biological viruses. It is a subfield of microbiology that focuses on their detection, structure, classification and evolution, their methods of infection and exploitation of host cells for reproduction, their interaction ...
Spacer acquisition. When a microbe is invaded by a bacteriophage, the first stage of the immune response is to capture phage DNA and insert it into a CRISPR locus in the form of a spacer. Cas1 and Cas2 are found in both types of CRISPR-Cas immune systems, which indicates that they are involved in spacer acquisition.
Laboratory diagnosis of viral infections. Purpose. test for viral infection. In the diagnostic laboratory, virus infections can be confirmed by a myriad of methods. Diagnostic virology has changed rapidly due to the advent of molecular techniques and increased clinical sensitivity of serological assays. [1]
Realms. Adnaviria. Duplodnaviria. Monodnaviria. Riboviria. Ribozyviria. Varidnaviria. A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. [ 1] Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. [ 2][ 3] Viruses are found in almost every ...
Virus quantification. Virus quantification is counting or calculating the number of virus particles (virions) in a sample to determine the virus concentration. It is used in both research and development (R&D) in academic and commercial laboratories as well as in production situations where the quantity of virus at various steps is an important ...
