What it is
Spigot is a detection name associated with adware, potentially unwanted applications, and browser components distributed in software bundles. It can change search or homepage settings, add extensions, display advertising, or collect browsing-related data. It should not be confused with SpigotMC, the unrelated open-source Minecraft server software.
How it works
An affected installer may present extra offers in small print, use preselected choices, or come from a download site that repackages another program. Added browser components can redirect searches or insert promotions. Exact behavior varies between bundles, so the detection path and installed extension or application name help determine what changed.
Key points
A potentially unwanted classification is based on distribution or behavior and is not the same as a destructive virus.
Removing an extension may not restore changed search, notification, proxy, or startup settings.
A Spigot alert involving an approved Minecraft server package needs careful path and publisher review.
What to do
Uninstall unfamiliar recent applications and remove unapproved browser extensions.
Reset altered browser settings and revoke unwanted site-notification permissions.
Run a full scan for related bundlers, tasks, and advertising components.
Use official download sources and submit a trusted SpigotMC file for false-positive review if needed.
