We have received reports of various websites that display a fake Firefox update alert and then prompt you to download a "Firefox update" or "Firefox patch" file. This is a scam tactic trying to trick users into installing malware.

What you can do if you spot malware

1. Never save and open/run unsolicited files!
2. Report the web forgeries to the Google Web Forgery site.
