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.
Products of Photosynthesis. The photosynthetic process produces several products. The first product, and primary reason for the process, is simple sugar. This sugar, called glucose, is the end result of the conversion of solar energy to chemical energy. It represents stored energy that can be used by the plant, or consumed by other organisms. Oxygen is also a product of photosynthesis. This oxygen is released into the atmosphere through the plantâs leaves. Water is also a product of photosynthesis. This water is produced from the oxygen atoms in the carbon dioxide molecules. The oxygen molecules released into the atmosphere come exclusively from the original water molecules, not from the carbon dioxide molecules.
