What it is
Anti-spyware is a security tool that hunts down spyware - stealthy apps that secretly watch what you do, steal logins, or track your browsing. Think of it as the part of your protection stack that catches quiet snoops before they cash in on your data.
Why it matters
Spyware doesn’t crash your screen—it blends in. It can read keystrokes, siphon cookies, or peek at messages, causing account takeovers and privacy leaks without obvious signs.

How to judge an anti-spyware result
Use a tool that identifies the exact item, location, and action rather than one that only displays a frightening warning. A useful product updates its detections, quarantines reversible findings, and explains browser or privacy changes. After cleanup, check startup items, extensions, proxy settings, account sessions, and permissions because removing one file may not undo every change. A clean scan also cannot revoke credentials already captured by spyware. Change exposed passwords from a clean device and run a broader malware assessment if symptoms continue.
