IMPORTANT: Web blocking / RAM usage announcement

On January 27, we published a web blocking protection update that caused connection issues for many of our customers. As a side effect of the update, the product also spiked memory usage and possibly caused a crash.

We have triaged this issue and pushed a protection update that resolves it.

For our consumer solutions

Please read our forums post for guidance on how to update Malwarebytes for Windows. Malwarebytes for Mac was not affected.

If the above doesn’t resolve the issue, please reach out to support at support@malwarebytes.com.

For our business solutions

Please read our forums post for guidance on both on-prem Malwarebytes Management Console (MBMC) and cloud-based Malwarebytes Endpoint Protection (Cloud Console).

If the above doesn’t resolve the issue, please reach out to support at corporate-support@malwarebytes.com

The root cause of the issue was a malformed protection update that the client couldn’t process correctly. We have pushed upwards of 20,000 of these protection updates routinely. We test every single one before it goes out. We pride ourselves on the safety and accuracy of our detection engines and will work to ensure that this does not happen again.

Getting your computer or business back up and running is our utmost priority, as is rebuilding your trust.
