How CASTER got on my computer?
Like many potentially unwanted programs, CASTER can be installed on your computer as part of a bundle with another tool you downloaded from the Internet. Since CASTER manufacturer pays software developers for distributing CASTER within their applications, CASTER is often included as part of the installer.
CASTER is also often distributed with free games and simple, one-click freeware tools developed specifically with the purpose of getting CASTER onto as many computers as possible.
Usually, you have not only one CASTER problem, but a bunch of similar WIN32:PUPs.
