specific foreign substances in the body, such as pathogens like bacteria or viruses. They help the immune system to identify and neutralize these harmful invaders.
Viruses can attach themselves to host cells, bacteria, fungi, and other viruses for the purpose of infecting and replicating within these organisms. They require a specific receptor on the surface of the target cell to bind and gain entry for their replication process.
Viruses can infect animals, plants and bacteria, and the attachments vary. In animal viruses: Animal cells have a cell membrane. Viruses attach to certain proteins in that membrane. In plant viruses: Plants can also be infected with viruses. Since they have cell walls, viruses attach to those when infecting plants. In bacteriophages (viruses that infect bacteria): Special viruses called bacteriophages attach to the cell walls of bacteria by way of proteins.
They don't attach to sites, they attach to links or downloads. When you open up the software from a link or download, your computer is "infected."
Viruses can only infect specific cells that have the necessary receptors on their surface for the virus to attach to. Each virus is adapted to infect specific types of cells based on these interactions. This specificity limits the range of cells that a virus can successfully infect.
Viruses have to attach them selves by way of a protein called a recognition factor. They bind to receptors on the host cell and then lose their capsid (coat).

Spikes on viruses are made up of proteins that are used to attach the virus to host cells. These proteins play a critical role in allowing the virus to enter and infect host cells by binding to specific receptors on the cell membrane.
Certain viruses attach to only one type of cells because they have specific surface proteins that can only bind to receptors on that particular cell type. This specificity is necessary for the virus to gain entry into the cell and replicate effectively.
While worms do not need another program to attach themselves to, viruses do. Piggybacking refers to the way that viruses infect or attach themselves to legitimate programs or documents to sneak onto your computer and attempt to infect it.
