Malwarebytes Browser Guard is blocking Prime Gaming

[BigArachnotron]

Hello.

I was trying to log in to Prime Gaming when Browser Guard threw me a message:

Malwarebytes Browser Guard blocked this website because it may contain malware activity.

I reduced the font to make the message smaller as both picture and straight text took some space.

Could this be a false positive? I mean Amazon is targeted a lot.

I'd let you decide.

Thank you for your time.

Kind Regards - BigArachnotron.

Did you receive this error before or after your login attempt?  If after, ugh!  If before, knowing the URL you were attempting to access would be of value.  In the meantime, I will try to whittle down this 2KB URL to something that might make sense without beer.

amazon.com.mx has been whitelisted, though it was the construction of the URL that I believe was the cause of the block. Please allow 15-30 minutes for changes to take effect. Sorry for the inconvenience.  Also, please let me know if you encounter any further issues there.
