Spyware is a type of computer infection that transports your data back to its creator. Software of this kind has many uses, some of which are legal, such as:
Monitoring company computers to ensure no one is spreading sensitive information
User-consented tracking for targeted advertising
Parental control software to track children’s online activity
Website cookies to customize your browsing experience
Installing an antivirus can protect you from spyware.
While it’s preferable to stay ahead of spyware, install an antivirus and avoid disaster. If an infection has already happened, don’t panic—it can be resolved easily with a good antivirus scan.
