Computer viruses are never naturally occurring; they are always man-made. Once created and released, however, their spread is not directly under human control. A macro virus is thus a virus that exists as a macro attached to a data file.

Ribosomes are made up of ribosomal proteins and ribosomal RNA (rRNA). In prokaryotes, ribosomes are roughly 40 percent protein and 60 percent rRNA. In eukaryotes, ribosomes are about half protein and half rRNA.

Ribosomes consist of two major components: the small and large ribosomal subunits. Each subunit consists of one or more ribosomal RNA (rRNA) molecules and many ribosomal proteins (RPs or r-proteins). The ribosomes and associated molecules are also known as the translational apparatus.

A ribosome is a complex macromolecule composed of structural and catalytic rRNAs, and many distinct polypeptides. In eukaryotes, the nucleolus is completely specialized for the synthesis and assembly of rRNAs. The complete mRNA/poly-ribosome structure is called a polysome.

1.1. RNA Viruses. Human diseases causing RNA viruses include Orthomyxoviruses, Hepatitis C Virus (HCV), Ebola disease, SARS, influenza, polio measles and retrovirus including adult Human T-cell lymphotropic virus type 1 (HTLV-1) and human immunodeficiency virus (HIV).

Being aware of the most harmful or notorious computer viruses impacting home users and businesses in 2020 provides the potential for minimizing risk and building defenses against them.

• Cyborg Ransomware.
• GoBrut.
• Jokeroo.

Adware. The number of sources define BonziBUDDY as spyware, a claim the company disputes. Spyware Guide’s entry on the program states that it is adware. Anti-virus company Trend Micro classifies the software as adware in their spyware/grayware listings, but not malware.
