Malwarebytes Adopts Aggressive PUP Policy

July 26, 2013 | BY

In the past, Malwarebytes Anti-Malware has detected only PUPs, or Potentially Unwanted Programs, that were mostly harmful and deceiving. Our users expected more and so we’ve revised our policy to include PUPs in our database that most of our users find annoying or misleading. Within the next few days, detection for many new variants will be added.

Malwarebytes feels most of our users have no knowledge that these PUPs were installed and would like them removed. Several thousand forum posts and support tickets confirm our standpoint. Ranging from difficult to uninstall applications to software that makes you opt-out, we’ve had enough of it all!

We invite all antivirus companies to join our fight, not only against malware, but also against unwanted and undesirable software. The only way we will make a difference is collectively.

    Good idea. Those PUPs usually show up when you download freeware and are hard to detect. Thank you Malwarebytes.

    The problem with PUP detections is that it creates false positives. My several attempt to fix the issues with the PUPs ‘detected’ by my jigsaw puzzles at http://www.JigsawADay.com have been met with only generic push-button responses from MalwareBytes. The latest generic non-response is what lead me to this post.
    Other software creators have this issue too, from what I’ve read online. In my case each jigsaw puzzle is treated as a separate program, and because a million people aren’t using it, MalwareBytes hasn’t taken the time to verify that it indeed doesn’t do anything harmful. The puzzles don’t download themselves; my visitors have to click on a link then confirm they want to download and run the puzzle. I’ve had TotalVirus.com scan both my website and individual puzzles, and MalwareBytes is the only one that squawks about them, and it never gives a logical reason for flagging the puzzles.
    MalwareBytes’s ignoring this issue and classifying them as PUPs without reasonable cause is harming my business and costing me income. I’m starting to wonder if a lawsuit is the only way I can get their attention on this matter.

    Sorry, meant to say “VirusTotal.com, not TotalVirus.com.

    Why does your PUP detection not find PC Optimizer Pro? This thing was silently installed and is almost impossible to eliminate.

    I can’t tell the good pups from the bad ones a lot of the time, maybe I should just delete this trail version of Maywarebytes and stop pulling my hair out!

    Problem I have with MBAM Ver 2.1.4.1018 is in settings I have chosen to ignore “PUP’s and MBAM insists on ‘Removal’ (PUP is ‘local appData’ Security Preferences for Google Browser application) The last version of MBAM didn’t do this, MBAM when overboard regarding PUP’s user control.

  • John Yungton

    Version mbam-setup-2.0.4.1028 didn’t do this, in MBAM settings under detections, ‘ignore’ worked for PUP’s. It’s a good product, In MBAM’s reaction to users PUP alarm request(s), the programmers’ created a small glitch.
