PUP.Optional.Legacy is a term used to indicate the potentially unwanted program on the computer. The detection name has been used by AdwCleaner and Malwarebytes anti-malware, so if you are using another anti-malware tool, you can receive different results, e.g. PUP.Optional.Legacy[key], Conduit, or Chrome Search Provider. However, the main idea means the same – your device is infected with the PUP. The warning about this intruder may appear out of nowhere because of the initial infiltration moment is usually not related to any adware-type symptoms. Adware programs, similar to other potentially unwanted applications, infiltrate system through bundling and then start delivering intrusive commercial content to your browser directly.[1] However, additional background processes that are used for victims’ tracking can make your computer run slow.
