I downloaded firefox update Firefox_72.6.js
I watched a video on Youtube and than looked through the comment section to read the comments. The YouTube channel user had a comment with a link to his personal website. I clicked the link and it immediately took me to a website that looked like a Firefox website. It said my firefox browser was out of date and asked me to download a file. I wasn't thinking and I downloaded the file and gave it permission to run. I immediately realized what I had done and I ran task manager and killed the running process. The file name was Firefox_72.6.js. The file was located at: https://dl. dropboxusercontent .com/ s/4xs37admbmtchrl/Firefox_72.6.js?dl=1
I haven't experienced anything bad on my computer because of this, but I don't think mozilla would have me download an update from dropboxusercontent .com. I did a search on Google for that filename, but I didn't find anything, and I wasn't able to find anything about it being a malicious file. Does anyone have any information or advice they can give me. I'm using Windows 7 and I turned on Security Essentials and downloaded the latest virus definitions and I'm doing a full system scan.

The Firefox_72.6.js file is FAKE.
It sounds like it could be a variation of the firefox-patch.js or similar named fake Firefox updates patches that used to be frequent for a while but thankfully it died off a good while ago now.
I used to keep track of the sites every time firefox-patch.j or such fake update files were mentioned as it was almost everyday at the time. https://support.mozilla.org/en-US/forums/contributors/712200
The firefox-patch.js or such files I mentioned were being served by malvertising Ads on some sites.

Now ! !
Thanks for the info! The file didn't appear to do anything. I scanned my laptop with Security Essentials and it didn't find anything. I uninstalled Firefox and reinstalled it, than rebooted in safe mode and ran the virus scan again. I made sure Windows has all the critical updates. Windows is behaving normally and there are no programs using up resources, so everything appears normal. I can post a copy of the js file if anyone is interested, but its kind of long.
Contact YouTube and explain the problem. Now ! !
Excellent advice !
