The last big Windows update crashed my computer and it wouldn't reboot. The repair shop copied almost everything and installed new Win10.  In the process Malwarebytes was lost.  My subscription expires 5/18/18 and I have the ID# and Key #.  When I tried to reinstall it,  with the ID and Key numbers, all I got was Premium 14 day trial and the "activate license" block didn't show and to purchase a license.

Yes.  I tried entering it again and it came back that this account is "blacklisted".  Why and what does that mean.  My account is paid thru May 14, 2018.

It means the key needs to be reset to allow activation. Lets try the quickest solution.

Create a Malwarebytes Account using the following link: https://my.malwarebytes.com/en/register

If you have purchased the product through us, you can use the same email to register for the account.

Once you can login into your account you could deactivate on the device where your product was wiped off and reset your license key.


If that does not work you will need to do the below.

For licensing issues, you'll want to reach out to our online support at 


Usually, support will take 2/5 days or more since support is busier than normal at this time to get to your request.

Please be patient

Business Hours: Monday - Friday, 6am to 6pm Pacific
