This happens when a detection is accomplished through heuristics. There is no such thing as a heuristic virus. As a technical concept, everything in malware detection is done via heuristics.
Photosynthesis is the process in which plants (also autotrphoic protists and some bacteria) use light energy, from the Sun, to make sugars and organic food molecules from CO2 and water (H2O). This process is essential for the formation of not only energy, but also for the formation of glucose for purposes of structure.
Photosynthesis does not occur at night when there is no sunlight. Glucose is the main basic energy storage molecule. It is also the basis for many other compounds, like the cell wall, and starch that is made during photosynthesis. <br /><br /> The process of photosynthesis doesn't require glucose. Photosynthesis is the process of plants converting carbon dioxide from the air and water to usable energy (in the form of glucose), with oxygen as a waste product. The word equation for it is as follows: carbon dioxide + water -------------------------------------------> glucose + oxygen.
