Mal/JSRedir-F is detected on web pages -- it detects javascripts embedded in web pages that are designed to redirect you to a known malicious website.  In itself it is not serious, but the websites you are redirected to are usually designed to install malware on computers through whatever means possible.  Luckily, only a few of them target OS X.

Sophos has an entire family of detections named JSRedir, and they all detect specific kinds of Javascript redirection techniques found on web pages.  If the content was cached before it ran in your browser, SAV will prevent you from being redirected.  If it instead loads into memory first and then gets cached, you've likely already been redirected to a new web page in your browser.

You likely got it by clicking on the wrong search result in your search engine.

Interestingly, Mal/JSRedir-F just got flagged up via the automated systems today -- it was first seen in July 2011, has been detected on over 1400 of our customer's systems, and has had almost 4,000 hits.  After being dormant for a while, reports spiked on the 25th, and it is currently running as one of our top 100 detections reported.

As I stated previously, it's a malicious piece of script added to web pages to redirect you to attack sites.  As it was detected, you didn't go to the attack site, so it never succeeded in dropping malware on your computer.
