Simply speaking, we can classify spyware under its feature related to user, namely, it is designed for general user or special user. The former is called general user oriented spyware, and the latter is called special user oriented spyware. We contrast their features as follows.
General user oriented spyware is designed for users whom designers do not know or understand. In order to ensure it can run on victim computers as many as possible, this kind of spyware should be compatible with various operating systems. Generally, it implements relatively simple functionalities and runs in client mode. For the whole spyware system, its value comes from the large number of victim computers. It does not care who is its victim computer but cares how many victim computers it has.
Special user oriented spyware is designed for individual users whom designer know very well. For example, designers can utilize features of victim computer such as its version of operating system, installed utilities, and even habit of user to develop a customized spyware. This kind of spyware usually has more complicated functionalities and is difficult to uncover through common anti-spyware tool. To enhance flexibility, some of them run in server mode.
As a matter of fact, the first kind of spyware usually cannot bring a big danger to you. Your data is probably stolen but there is little chance to be analyzed by manual because there are too much victims as you. In general, this kind of spyware makes money by distributing ads. That is, they are usually adware. If you feel uncomfortable to see unexpected ads, you can use a reliable anti-spyware or anti-adware to clean.
The real dangerous spyware is from the second category. Nevertheless, if your computer has not special important data, you never worry about it.

No one can help you. If you face a secret spyware but not designed for you specially, you can clean it with a good anti-spyware or do not care it because it usually utilizes your computer to make money instead of spying your data.
