Thank you for answering
1 - May I request this topic to be moved to the correct section? I personally find it a little confusing to where should I open it since I'm not even sure which exactly component is responsible for the problem.
2 - I already gave a feedback following @Berny instructions, and others might have done the same because it's a problem affecting everyone judging by the other topic.
My goal opening this topic wasn't to resolve my personal case, since as I've mentioned before I can work around it by exiting Kaspersky before I log in (which isn't the best solution), but to give a feedback about this problem that might been affecting other users that are unaware of the cause.
While affecting just a specific page (despite being a popular one) isn't much of a problem, causing browsers to consume too much resources is, so I believe this should either be looked by the support team (maybe contacting Crunchyroll if it's necessary), or if it's really a dangerous component, inform users about it like it does to other pages.
Whatever is the case, expecting users to opt-in the solution shouldn't be the best course to follow.
