Short bio

PUP.Optional.StrongSignal is a potentially unwanted program (PUP), specifically adware targeted at Windows systems.

Source and type of infection

Once PUP.Optional.StrongSignal is installed, this PUP pushes an excessive amount of pop-up and embedded advertisements on websites users visit.

StrongSignal is marketed as a tool that shows the user coupons for merchant sites they are visiting; however, it actually just bombards the user with advertisements whether they relate to the website or not. PUP.Optional.StrongSignal is usually found bundled with other software, which may be legitimate or potentially unwanted in nature.
