Spyware is software that gets installed on computer without users consent. Spyware can cause harm by taking partial control of computer and by compromising privacy. Spyware can collect personal information such as browsing habits (primarily for marketing purposes) and sensitive information such as credit card number. Spyware can also take control of computer and install additional software, redirect to malicious website and install virus.

Spyware vs Virus/Worms
Spyware do not self-replicate themselves like Virus/Worms. Spywares are primarily used to trigger other actions such as taking control of computer, stealing personal information and installing other malicious software e.g. virus.

How does Spyware enter system?
Spyware typically pretends to be useful software (Trojan) or comes bundled with useful software. Spyware can also get inserted into computer by using security vulnerability.

Adware vs Spyware
Adware is any software program used to display advertisement. Adwares are generally spyware too because these programs have to spy on user’s browsing activities for displaying relevant ads. Adware are not necessarily surreptitious and malicious though, as advertising revenue might be used to provide free or reduced price software and users might consent to receiving advertisement for cost saving. But caution is required to prevent any malicious software entering the system.
