Virdem overwrites the host with its own code and saves the original program at the very end. It was a direct-action virus and did not spread fast. [failed verification] It infected only files that had a COM extension. [5] When an infected file is run, the next uninfected program becomes infected.
Direct action is a term for economic and political behavior in which participants use agency—for example economic or physical power—to achieve their goals.

Examples of vertical transmission include hepatitis B virus and HIV, where the baby is born already infected with the virus. [116] Another, more rare, example is the varicella zoster virus , which, although causing relatively mild infections in children and adults, can be fatal to the foetus and newborn baby.
Often simply called an antiviral. A class of antimicrobial medication used specifically for treating diseases caused by viral infections rather than ones caused by bacteria or other infectious agents. Unlike most antibiotics, antivirals typically do not destroy their target viruses but instead inhibit their development. They are distinct from virucides. assembly The construction of the virus ...
Viral pathogenesis is the study of the process and mechanisms by which viruses cause diseases in their target hosts, often at the cellular or molecular level.It is a specialized field of study in virology.
