    en.wikipedia.org/wiki/Form_(computer_virus)

    Form has a number of variants. The widely documented versions are as follows. Form.A is a common variant of the original, where the clicking payload occurs every day, as opposed to just the 18th. Form.B is a minor variant of the original, with the clicking payload set for the 24th of each month instead of the 18th. It was a rare find in the ...

    en.wikipedia.org/wiki/Capsid

    A computational model (2015) has shown that capsids may have originated before viruses and that they served as a means of horizontal transfer between replicator communities since these communities could not survive if the number of gene parasites increased, with certain genes being responsible for the formation of these structures and those ...

    en.wikipedia.org/wiki/3D_modeling

    The 3D model can be physically created using 3D printing devices that form 2D layers of the model with three-dimensional material, one layer at a time. Without a 3D model, a 3D print is not possible. 3D modeling software is a class of 3D computer graphics software used to produce 3D models. Individual programs of this class are called modeling ...

    One of the few solid theoretical results in the study of computer viruses is Cohen's 1987 demonstration that there is no algorithm that can perfectly detect all possible viruses. [ 4 ] Cohen also believed there are positive viruses and he had created one called the compression virus which spreading would infect all executable files on a ...

    The science fiction novel, When HARLIE Was One, by David Gerrold, contains one of the first fictional representations of a computer virus, as well as one of the first uses of the word "virus" to denote a program that infects a computer. [6] [7]

  9. Viral replication - Wikipedia

    en.wikipedia.org/wiki/Viral_replication

    How a virus releases from the host cell is dependent on the type of virus it is. One common type of release is budding. This occurs when viruses that form their envelope from the host's plasma membrane bend the membrane around the capsid. As the virus bends the plasma membrane it begins to wrap around the whole capsid until the virus is no ...
