Red Scam Warning in Browser

A little while ago, shortly after booting the computer and launching Chrome, the Yahoo! home page got replaced with a red page about some sort of malware attack on my computer, complete with recorded voice warning. Considering that Avast and Malwarebytes both found nothing, how concerned should I be?

Microsoft Edge Hacked


Check the above thread (lengthy, but worth the read)

Same thing happened to me today on Edge. Apparently only a nuisance.

That link was 244 days old.

Normally, you'd disconnect from the internet, use Task Manager to close the browser, and run Ccleaner on all browsers that exist on the system, to clear cache, cookies, history, etc. Then, flush DNS, and run a malware scan. If nothing is found, you should be fine.

Under the current circumstances, since I don't currently have CCleaner, should I trust a freshly downloaded copy?

I would. Or, you can manually clear out all your browsers.

I already used CCleaner, and there's still no sign of any malware. I think what I had was an amateur attack, unless it's hiding until I least expect it.

Cheers!

As an afterthought, is it likely that this is one of the types of attacks which GPT protects the system from? I'm wondering, because a friend of mine who does IT recently told me that closing Chrome with the close button should not have worked as well as it did.
