Sometimes such software is mixed together with other types of software such as Adware, which are installed stealthily on your machine and you might not need them. Software bundling is a completely legitimate practice that can accumulate enormous profits for whomever exploits and develops such advertisement software.

The aforementioned ones are the usual ways Adware enters your PC.
