          I'd copy the file and look at it in a text editor and hex editor to see if there's anything revealing. Might have to run it through a Javascript bytecode decompiler or something too.

          Anyone want to zip up the file and make it available for download?

              Same issue for me. Opera browser keeps generating this threat. Website visited is irrelevant to its creation.

                @wanderlei So after you have cleaned cache and the directory mentioned on the alert, you get the alert again in the first page you visit?

                  @tjall, just pasting this part of the URL you posted in Notepad++ triggers Windows Defender for me (in the Notepad++ backup file that gets auto-generated for the document):

                  lookmeet.png

                  I suggest others with this problem look in the detected file to see what URL is listed. Just in case, do a screen shot of it or something so it doesn't trigger defender when users visit this thread

                    @leocg @vendimia Вам нужно попробовать узнать, с какой страницы он идет. Предположим, что это не ложное срабатывание.

                    ни с какой страницы. просто при открытии браузера

                      I have the same issue. Is it clear by now if it is a real virus, or what exactly it is?

                        What happen with me, I got alert from defender, I removed the suspect file, I start browsing completely different site, the same alert from defender again. This happened 6 times across different sites.

                        I downloaded and ran malwarebytes but everything thing was clean.

                        I run a few extensions, I will disable all of those and see what happens.

                          I suspect you're right. It's not a bad web page. Not likely that we're all on that web page. This has been happening for just a few days. I think it's a false positive. When I run Super anti-spyware or Spybot on the cache, it picks up no threat. But i could be wrong.

                            Same thing just started popping up for me too. Only with Opera. I am starting to wonder if there is something going on with Windows Defender and Opera. We all cant be visiting the same sites who have posted in this thread.

                              I just removed a video dowloader extension. And It worked. Hope it help.

                                    @wanderlei So far I didn't get such alert from Windows Defender, so it seems to me that the problem is related to a specific site or to an extension.

                                      Removed the SaveFrom.net video upload extension. The threats are gone.
                                      Who has this extension?

                                          Very same problem here, it started to happen from 02/09 browsing ansa.it website: history for the last days recorded negligible browsing with just the usual 3 tabs opened (youtube (for music) , gpone and amazon; no extension added in months.

                                          A full disk scan with Defender found the same threat in 4 different cache files and removed them: alerts still coming from the above mentioned file regenerating in js cache but any new full scan now is clean.

                                            @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.
