|In regards to generic PUP.x!ct|
This from the McAfee web site:
This software is not a virus or a Trojan. It is detected as a "potentially unwanted program" (PUP). PUPs are any piece of software that a reasonably security- or privacy-minded computer user may want to be informed of and, in some cases, remove. PUPs are often made by a legitimate corporate entity for some beneficial purpose, but they alter the security state of the computer on which they are installed, or the privacy posture of the user of the system, such that most users will want to be aware of them.
This symptoms of this detection are the files, registry, and network communication referenced in the characteristics section.
This is not a virus or Trojan. PUPs do not "infect" systems. They may be installed by a user individually or possibly as a part of a software package (in a bundle, for example).
