As you sense your device has been infected with spyware, you should run a scan with your existing security software/AV for making sure it has cleaned up all malicious contents.

Spyware is a type of malicious software (malware) that can enter a user's computer and gather data without their consent. Spyware can also monitor and copy text, apps, websites, and documents a user enters or visits. Some spyware can also access a user's camera and microphone to record them.

Spyware can collect information such as:

1. Keystrokes
2. Screenshots
3. Authentication credentials
4. Personal email addresses
5. Web form data
6. Internet usage habits
