ALERT: Fake Firefox & Chrome Update JS file
ALERT! There are some sites, including Yahoo.com that have popups that look very convincing to immediately download a Critical Firefox or Chrome update. Then a download box appears with an option to run or save the update named somefilename.js. Again, it looks really legit, but it is not!
- The download box will never just automatically appear at legitimate sites, you would have to click to start the download in most cases.
- Real browser updates are .exe files, never .js - that is a javascript that will most likely install something very bad into your browser.
- Check the URL (www .xxx .com) Chrome is google.com and Firefox is mozilla.org
These simple things to watch for will always save you in the end.
