There is no way to "clean" it from your computer because there is nothing to clean.
This has happened on all of my devices, desktop and mobile. No scan of any kind reported any infection, including a browser hijack.
I was able to block at least some of these by placing a domain reject blacklist entry of *.amazonaws.com in my router's domain blocking table. That, however, works only for when I am connected to my home wifi.
Don't run around wasting time looking for a way to remove the" virus". You don't have malware, and no, your browser has not been hijacked. Sites claiming a sure way to remove such due to this issue are, very likely, themselves trying to scam you (which is likely to be the point of the pop-ups themselves!).
Don't believe ANYTHING bleepingcomputer.com says about this. They will waste hours of your time, have you scan and install their "tools" literally for days on end, and you will make exactly zero headway with this issue. Those people do NOT know what they're doing, at all.
What we SHOULD be doing is contacting whatever customer service Amazon has set up for their cloud services, because one of their customers is the source.
