In the event that an unfamiliar application is consuming a large amount of CENTRAL PROCESSING UNIT, memory and disk space, it may be taking information or perhaps tampering with files.
Anti virus programs possess a huge bunch of code snippets known as autographs that they can check for when ever analyzing documents or running new courses. If they will ran most of these signatures whenever a file was run or accessed, it might be impossible for a computer to control. So they use heuristics, which detect suspect behavior. An example is any time a program attempts to access a whole lot of files quickly.
