A virus that infects and causes harm to its host is called a pathogenic virus. These viruses can lead to various diseases by disrupting normal cellular functions, triggering immune responses, or causing cell death. Examples include the influenza virus, HIV, and the Ebola virus. Pathogenic viruses can vary in severity, with some causing mild symptoms while others can be life-threatening.
A virus is something that infects cells and makes them produce more of the virus.
A bug virus is a computer virus that infects software programs and causes them to malfunction. It can spread through infected files and disrupt the normal operation of a computer system. Bug viruses are typically designed to either cause harm to the system or steal sensitive information.
HIV. Causes significant reduction in the amount of CD4 cells as the virus attacks it.

Viruses are designed to harm the computer. These no such thing as a virus that does not cause harm to computers. If your virus scanner detected a virus, the damage is already done.

Virus' don't help computers, they're given the name virus because they harm your computer, my suggestion, don't get a virus.
First I'll answer what a bacteriophage is. A bacteriophage is a type of virus that infects a bacterium. These phages can be either virulent or temperate. Virulent phages are capable of infecting and even killing the bacterium it has infected. Temperate phages usually do not cause harm. Its DNA is incorporated into the bacterium's DNA creating what is called a prophage. I don't really know what you are looking for when it comes to "harmless". A harmless phage is one that either only infects a specific bacteria and not the cells of say a human. This is called phage therapy. It is used for bacterial infections in human. The phages kill the bacteria but doesn't infect the human cells. It used to be big in the former Soviet Union but has kind of fell off. I do believe that it is starting to pick up momentum again however. The second thing i guess a harmless phage would mean is the temperate phage that does not harm the bacteria it has infected. If this is what you are looking for, google temperate phage or prophage. You should be able to find the info you need/.
In amazonia there is a mushroom that infects ants - consumes them and grows stalks from the carcass. Some mushrooms are highly poisonous.
