A Malwarebytes update is now up and running that rectifies a bad release that caused the main process of the security product to slog down computers to the point where they almost came to a halt.

After learning of the original bad update, company officials quickly responded by releasing a fix to address the bug. The company is urging users to install the most recent update and reboot computers. Two system restarts might be required, because stabilizing the system doesn’t always take place after the first one, company officials said.

Malwarebytes officials said the problem was because of a protection update shipped on Saturday morning.

“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,” the company said. “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.”

The company recommends users to update Malwarebytes and to restart computers, but in case this doesn’t address the high CPU usage bug, they should download and run MB-CLEAN. If this second workaround doesn’t make any difference either, users should get in touch with the company via its forums.
