Two of the most common types of malware are viruses and worms. These types of programs are able to self-replicate and can spread copies of themselves, which might even be modified copies. To be classified as a virus or worm, malware must have the ability to propagate. The difference is t...
In computer security, a Trojan is a type of malware that can wreak havoc on computer networks. Unlike a virus, which relies on a host program to spread itself, a Trojan relies on unwitting users to let it in.
Viruses are microscopic parasites that lack the capacity to thrive and reproduce outside of a host body.
With help from the host, viruses are then able to multiply. That's good for the virus but generally bad for the host. Without the host cell, a virus cannot survive long term; however, it does have a short window of time during which it can function in hopes of attaching to (...
Why are viruses not classified as prokaryotes or eukaryotes? What structure will you find in a prokaryotic cell? What is the difference between chromatin and a nucleosome? Are animalcules prokaryotes? Compare and contrast bacterial and eukaryotic ribosomes. ...
Are There Any Exceptions To Cell Theory? Viruses are considered to be an exception to cell theory, because though they perform the essential functions of a living entity, yet they cannot replicate or reproduce, despite having theirgeneticmaterial present inside them. This violates the third postulat...
What are the mechanisms by which mature enveloped and non-enveloped viruses enter and leave a host cell? Briefly describe the processes and name an animal virus for each. Virus enters a host cell, "enslave" host cell machinery and replica...
Any cleanroom staff must understand the key distinctions between the two. The industry-recognized definitions of each are as follows: Aseptic: A surface, object, product, or environment has been treated such that it is free of contamination. Bacteria, viruses, or other harmful living organisms ca...

Those new viruses find and take over more CD4 cells, and the cycle continues. This leads to fewer and fewer HIV-free, working CD4 cells. HIV can destroy entire "families" of CD4 cells, and then the germs these cells fight have easy access to your body. The resulting illnesses are called...
