PUP or Malware?


Recommended Posts

I was doing some testing on behalf of a user in another thread and discovered that Malwarebytes 3 is classifying the two versions of its installer (32 bit and 64 bit) differently, one as PUP and one as actual malware (adware) because of the differing vendor names being used (one starting with PUP.Optional and the other starting with Adware.):


The software in question is PowerISO and the two installers are available here:


I would suggest changing one of the classifications to match the other for consistency since they are obviously the same threat/PUP/adware and one being targeted as malware while the other is classified as PUP could have far reaching consequences due to how Malwarebytes 3 differentiates between the two categories of detections, both in its display as well as in its settings and how they may potentially be handled by the user should they alter settings for PUPs.

One might make the argument that anything classified as adware is technically PUP, not actual malware and therefore should be categorized always as orange/PUP, not red/malware, but doing so without manually changing every Adware. entry in the database would require new engine syntax to classify any def using that prefix as orange/PUP meaning the Devs would have to modify the engine/SDK so a simple find/replace routine through the raw database might be easier for now and perhaps a memo to the other members of Research regarding adware classification.
