With the number of malware increasing, there should be Protection measures to ensure users feel safe and sound.
Malwarebytes Corporation is one of the players on the field. The creator of Malwarebytes anti-malware software for Microsoft Windows, macOS and Android. Its product has also included protection against ransomware, exploit, and malicious websites.
So far until 2018, the company has pushed more than 20,000 perfect patches for its software. But apparently, two poor ones have made users angry.
On January 27th, two updates have been released as part of the company's continuous protection update cycle which installs automatically without user interaction. But those updates have caused sudden spikes in CPU and RAM usage, sometimes so severe that Malwarebytes crippled users' systems.
In the company’s forums, people complained about the software hogging 90 percent or more of memory and CPU resources. Some users' system failed to restart the real-time web protection after the feature turned itself off.
In short, the updates made Malwarebytes to eat a lot of resources to a point of making systems entirely unusable.
According to Malwarebytes, the problem lies in the protection blocks feature. The company has been working to improve its software in this area by adding "enhanced detection syntaxes" to include block categories in product definition. However, an "oversight" can result in failures.
Because the syntax controls were not implemented in the new detection syntax, it deformed the software's detection procedures. As a result, resource usage spikes dramatically.
"The root cause of the issue was a malformed protection update that the client couldn't process correctly," said Malwarebytes administrator Marcin Kleczynski.
The failed update impacted Malwarebytes for Windows Premium, Malwarebytes for Windows Premium Trial, Malwarebytes Endpoint Security (MBES), and Malwarebytes Endpoint Protection (Cloud Console).
"We published a protection update that caused connection issues for many of our customers. As a side effect of the web protection blocks, the product also spiked memory usage and possibly caused a crash. We have triaged this issue and pushed a protection update that resolves it," said Malwarebytes CEO Marcin Kleczynski.
Users have reported that the protection update patch makes the software stable, and no longer destroying their CPU and RAM usage.
Those that were impacted by the 2 botched updates, they need to install the fix and may require to restart their systems a few times to resolve the issue.
