Problems with spyware:

Several problems present themselves when a user has spyware on their system.

Pornographic advertising:
Spyware creates targeted advertisements can be a problem. The ads will be created from information such as websites and advertisements visited previously. If children are using the same computer, this can be a problem. If the adult user visits a pornographic site, the minor could receive targeted advertisements which contain pornographic material. Sometimes the targeting of ads can be for pornographic advertisements without anyone having visited adult sites.

Annoyance:
Spyware can be a huge annoyance to computer users. Created Pop Up ads often appear when web pages are opened or closed. This can cause hours of wasted effort because many of the Pop Ups create more popup ads as they are closed, in an ever expanding cycle.

Computer Memory and CPU Resource:
Some spyware allows the unauthorized use of computer memory and cpu resources. This includes running programs while a PC is not busy. However, increased use of a computer memory, processor and harddisk increases the wear and tear on the components, and reduces its functional lifetime. In some cases resources are used for malicious purposes, such as mailing spam or viruses to everyone in your addressbook.

Lose control of your PC:
Spyware can change browser's homepage and other settings without the user's knowledge or permission. These changes can include turning off firewall and security protection so the spyware can communicate with external resources, making them potentially dangerous.
