WithSecure process consumes an enormous amount of RAM

tilman

Hello everyone,

One of our employees has been experiencing a problem for a week now: according to Task Manager, this process is consuming an extremely large amount of RAM. Even restarting the computer or manually terminating the process has not helped. It keeps coming back.

What can I do?

Many thanks in advance!

Best regards,

Tilman

Hi @tilman

Thank you for reaching out and providing such a detailed description of the issue, along with the troubleshooting steps you’ve already taken. We appreciate your proactive approach!

The "WithSecure plugin hosting service" is a core component of our security solution, and while some memory usage is expected, the levels you’re describing do seem unusually high. Your plan to update, restart, and potentially reinstall the software is exactly what we would recommend as initial steps.

A few additional suggestions:

• If you haven’t already, please check for any recent Windows or third-party software updates that might coincide with the start of this issue.
• You can also try running the WithSecure Support Tool to collect diagnostic logs. These logs can help our support team identify any underlying issues.
• If the problem persists after a clean reinstall, please open a support ticket and attach the diagnostic logs for further analysis.

We’re here to help, so please keep us updated on your progress or let us know if you need step-by-step guidance for any of the above actions.

Thank you for being part of the WithSecure Community!
