Spyware comes in various forms. These can include:
Keyboard loggers that record your keystrokes you type on your device. This is handy for bad actors that want to glean your passwords, credit card numbers, and other important personal information.
Adware that records a user’s web activity and then uses the information to direct pop-ups and spam at users.
Browser hijackers that reset your browser home page and other links. These allow the bad guys to redirect your traffic to malicious websites or to sites they make money from for directing traffic there. Browser hijackers can also be used to track your online habits.
Modem hijackers take over your device’s cellular or WiFi connection, making calls to 900 numbers and pay-for-play sites like porno sites, to place charges on your cellular bill.
