@Svarnoy60 - I do not use the savefrom downloader. I have "Force Download 1.08" at ashus.ashus.net. and I have "HD Video Downloader". But I don't use them. I use IDM instead. I will disable the ones I don't use. But this is a hit or miss exercise. Why can't Opera troubleshoot this? I can't open the suspect js cache files because Defender quarantines them.

Basically, you already answered your own question. So far there doesn't seem to be a way to reproduce the issue and, therefore, there isn't a way to find out what the problem would be.
Those getting the alert should contact Microsoft and ask why the alert is popping up.

The alert pops up when some task in Opera re-creates the file named c0ac6bec106548d2_0 and it happens just leaving the browser open on the home page.

You can access the quarantined file closing Opera (just to prevent code execution) and restore them from Defender's history.

Most probably the file is being cached from a visited page or from an extension. That's why me and others don't see the alert. And that's why Microsoft needs to say why the file is being considered a threat.

@leocg Thanks for the advice. But the last time I called MS, I told a tech person in the Philippines that I must have deleted a Microsoft system font. She said the only way to fix it was to re-install Windows 10! I fixed it after researching the matter and copying Segoe font into the Win font folder. Most are clueless. One in 100 have more knowledge than me.

@burnout426 The weird thing is yesterday I got the same result trying to copy & paste that url to different text file - MSE started poping and deleting each file with the url.
But, today it doesn't - the file exists.
Wtf, are you sure you guys don't have the file still?
Please try to search "c0ac6bec106548d2_0"Seems like the Microsoft AV likes the file now... :S

I checked out the source of that one. It looks fine at least.

HD Video Downloader
Link? I see a Chrome app for it, but not an extension.

Removed the SaveFrom.net video upload extension. The threats are gone.
Who has this extension?I had it, though I'm not sure it was it.

@burnout426 - i think this is it: https://addoncrop.com/en/
But what is the suspect link now? Someone sounded like we know what it is.

The Youtube Downloader one? I checked it out and it doesn't seem like that's the culprit. It does contain some obfuscated strings in its apps/scripts/background.js file though, so I wouldn't totally trust it without looking more into it and decoding the string escapes.

Upload extension or download extension? As in, is it this one https://addons.opera.com/en/extensions/details/savefromnet-helper/?display=en?
I installed that one and don't get the problem. I looked at the source briefly, but there's a lot of code in there.

Same, not getting alerts from defender anymore but I searched and found the same file.

The file has link to https://lookmeet.tv/ a russian site.
I will delete file and disable extension and see if it regenerates again.

@wanderlei - Perhaps "https://lookmeet.tv/" is not the culprit.
I have 44,450 files in my js folder. I found "https://lookmeet.tv/" in 20 of those files. Yet I had no Defender warnings since 9-8 @11:24AM (ie over 24 hrs). Either it's not the threat or else Microsoft turned off the warnings for that site. But I'm no expert in this stuff.

@wanderlei - So perhaps MS got wind of this nuisance from various sources and adjusted Defender's virus signatures.
