Supsected virus on my pc

Hi there, I can’t find a similar topic. I have Avast Premier and every day it blocks stuff when I open chrome - which is constantly problematic - it won’t do things it would normally do. I also have free Malwarebytes and it is constantly blocking pups and a trojan, so my pc is infected with something. Could you help me please! I know there is a list of things I need to do to help you work this out, but I can’t seem to find it. TIA

Ok, I have found the article! I have attached the files

Do you have Chrome sync on ?

Thank you for your reply - that sounds like it would fit. Every day when I open chrome I have constant detetections. I will follow all the instructions. Though I can’t find out how to log out on my mobile - I guess I would need to remove the account then set it up again?
