Explain the various types of viruses with examples?
Answers
Answer:
Natural selection acting on random mutation is the mechanism which causes change.
VIRUSES CAN INCREASE THE NUMBER OF FATALITIES BY:
Spreading more efficiently by…
Decreasing lethality in some cases.
Shifting from spread by contact only, to a respiratory route.
Spreading to different species (more opportunities for transmission and sustainable mutational diversity).
HavIng a prolonged asymptomatic infectious period.
Intensify host behaviors (sneezing, coughing, having diarrhea) that spread infections.
Increase vial concentrations in organ systems (throat, lungs, intestines) which help to spread infection.
Increasing viability period. The time the virus can exists on various surfaces before becoming noninfectious.
Becoming harder to detect by…
Evolving a sudden immunological change by forming a novel hybrid virus.
Spreading into a new host species which is immunologically naïve.
Developing conformational changes on surface proteins that shield viral antigens from the immune system.
Attacking the immune system.
Having a high mutation rate.
Diminishing immunological response and memory, through the use of stealth and control of viral production rate.
Adapting a triad of infection strategies, lysis, budding, embedding in the DNA, which can be employed to manipulate, or hide from, the immune system.
Increase infection efficiency by…
Increases binding affinity.
Increasing the thermodynamic and kinetic efficiency of cellular entry through the plasma membrane.
Creating a different viral antigen presentation when on cellular surface then when on viral surface.
Increasing efficiency of self esembly.
In the case of viruses with low mortality rates…
Increasing mortality rate.

Virus is like a communicable disease that affect your system badly and make it unusable. There are many types of virus which comes in the system via various intrusive method. Such as
Ransomware: Ransomware is very dubious computer infection which is created by cyber criminals with the main motive to encrypt your various important data or file and demand ransom from innocent users.
Trojan horse: Trojan is highly-dangerous computer threat that silently enters into the system without consent. It drop a malicious code in the registry entries for automatic start-up.
Adware: Adware is dubious ad-supported infection that display lots of intrusive ads like banners, in-text links, pop-ups, commercial ads, etc.
Scam Pop-up: Scam pop-up is the perilous tech-support scam pop-up that urge users that their system has been infected with virus and convince them to call on tech-support number given on pop-up.
Browser Hijacker: Browser Hijacker is mainly a dubious domain that able to alter browser settings including default home page, new tab page and search engine of your working browser and cause redirection problem.
