What does grayware typically do in a computer system?

Grayware refers to software that may not be strictly classified as malware but can still have undesirable effects on a computer system. This includes any software that can create issues such as unwanted advertisements, system slowdowns, or altered system behavior, often without the user's explicit consent.

Unlike viruses or traditional malware, grayware can encompass a wide range of programs, such as adware, spyware, and potentially unwanted programs (PUPs). These types of software may not harm the system directly but can lead to negative experiences for the user by interfering with normal operations, consuming resources, or displaying intrusive advertisements.

Therefore, it accurately reflects the definition of grayware that it can make a system behave improperly by affecting its performance or altering its intended usage. This is why the choice that indicates grayware's role in making a system behave improperly is the correct answer.
