The ugsound site is a online radio site.

Not sure what warning you got as nothing comes up for me.

I moved this thread from Firefox for iOS (for iPhone/iPad) to Firefox section as your iMac has macOS.

What warning did you get?

It started with a spam email. Pretending to be from Bank Of America. I hovered over it and the sender was “chaseonline@ugsounddotcom”

I did not open the email or download anything. But then I did something stupid and went to the website itself “ugsounddotcom” I was on Firefox browser. I typed in the website in the search box so it popped right up. As soon as the site popped up, Firefox flashed a big warning sign. I got right out of the site, x’d out the site and turned off the computer. I was on the site for maybe 5 seconds. I got out so fast, I can’t recall if Firefox said it was a malicious site or if it said it was blocking the site. The Firefox security was on to block dangerous content and the Apple iMac firewall was on. I did not click on anything and I did not give any remote access. But maybe 5 seconds is all the site needed to get my computer files and documents. I did not download anything. I just brought the computer to Geek Squad at Best Buy to check for any type of invasion

It is an Ugandan radio station website that I believe is used as a phishing scam site. I am a real idiot for going to it. Same thing as clicking on the spam email

You aren't using a Proxy or VPN service?

You can do a malware scan, just to be sure.

The ugsound site is a online radio site. Not sure what warning you got as nothing comes up for me. I moved this thread from Firefox for iOS (for iPhone/iPad) to Firefox section as your iMac has macOS.

It came up as as warning of a malicious website by Firefox. It first came as a spam email pretending to be from Bank Of America. The sender address was “chaseonline@ugsounddotcom” I did not open the email or click on any link, but like an idiot, I checked out the website and that’s the same as opening a link. As soon as I got on the website, the Firefox warning come up. I was on the site for 5 seconds. I ex’d it out and unplugged computer. I did not click or download anything or give remote access. But still, these phishing sites only need a few seconds to know you opened their website. So I have to assume it got all my files. I brought the computer IMac to Best Buy Geek Squad. They are going over it the next 2 days. Geek Squad did show me that the Apple firewall was on and that the Firefox security was on to block dangerous content.

Thank you.. The computer is at Best Buy Geek Squad. They are running full diagnostic the next 2 days. Hoping the Firefox security blocked the website and the Apple firewall helped. Geek Squad did not see any downloads today in my files.

If you got the red warning page described in the below article, that loaded first, and you never actually visited the site.

How does built-in Phishing and Malware Protection work?

Here is what happened. I first got a spam email pretending to be Bank Of America. But the sender was “chaseonline@ugsounddotcom”

I did not open the spam email, bit I like an idiot, I typed in “ugsounddotcom” in the Firefox search browser and it sent me directly to the site. And the split second the site opened up, the Firefox warning box came on saying it was a malicious site. I was the site for maybe 5 or 6 seconds and then x’d out and shut off computer. I did not get a red warning page. I was on the malicious site and a Firefox warning box immediately popped up. Are you saying that that warning box actually prevented me from entering the site even though I was on the site?

Normally, if you visit a phishing or malware site, the page does not load at all because it is blocked based on its address. There is an example link in the article to see what the warning page looks like.

When you say there was a pop-up, a couple of different scenarios come to mind:

(1) The page opened a new popup window whose address is blocked. However, the original page was still there and that was fine.

(2) The page redirected to a different site, and that site's address is blocked. This could explain how the whole tab changed.

(3) The page loaded a blocked page in a large frame or an overlay in front of the page without leaving the original site.

(4) The page triggered an automatic download and Firefox's downlist list opened and said it was an unsafe download.

or

(5) The page loaded an ad ("malvertisement") which pops up a message (not based on Firefox's built-in list) telling you that you're infected in order to trick you into giving them money for security software/services.

Thanks for responding. Truly appreciated. Again, the best way I can explain is that I typed in the website “ugsounddotcom” directly into the Firefox URL search box and the website came up automatically without warning. Then a split second later, a Firefox warning message appeared on the website page saying it was a malicious site. I really didn’t read the entire message from Firefox so I don’t know if it said it was blocking the page/website or just warning me to get out. I was on the site for maybe 5 seconds. I x’d out and unplugged computer. Later at the Geek Squad, they showed me that the Firefox security block for dangerous content was on as was the Apple firewall. But until the scan is complete, I will not know if the malicious website was able to get into my computer or files. The Geek Squad did not see any downloads that were new this morning and I did not give permission for remote access or click on anything, but I was told that all it takes is few seconds to be in a malicious website and your screwed
