MBv4beta crashed on exit in Malwarebytes 4.x Beta Posted Monday at 02:33 AM · Edited Monday at 03:50 AM by 1PW Hello @tepitts: 2 hours ago, tepitts said: There are utilities that will scan and, if necessary, repair your registry. Quote One of the most common complaints we see on our forums, and from our users, concerns a particular category of program called “Registry Optimizers” or “Registry Cleaners” or “Registry Defragmenters”. For this post, we will just refer to them as registry cleaners. Malwarebytes official stance on such products are summed up rather nicely in the Malwarebytes Labs Blog: Registry Cleaners: Digital Snake Oil Hence, similar products would be rightly regarded as a PUP and would be flagged and quarantined by the Malwarebytes for Windows product. Thank you for your understanding.
