Why is the processor loaded at 100% when surfing the Internet?

Question

Computers

Good afternoon! The last week the computer began to buzz a lot, and the processor began to load at 100% when opening tabs in chrome, watching videos, etc. This has never happened before, even when opening 20 - 30 tabs. There are no viruses, what can be done?

Answer 1

As a rule, this starts after the launch of "Crome" Other browsers do not react this way. "Opera" for example.
