Title: URL:Mal threat detected on EVERY new or refreshed page in firefox
Post by: Briansdad on June 03, 2013, 05:55:07 PM
I get a URL:Mal threat detected on EVERY new or refreshed page in firefox, no matter what the URL is. Firefox and Avast (engine, defs, and program) are all up to date. Been going on for a few days. Ran a full system scan with 0 infections detected. What now?

Once you have deleted the malware with AdwCleaner could you run a fresh OTL scan so that I can see what is left

Yesterday I ran the Adwcleaner twice, he first time as "search." Then I noticed I needed to use "delete." Ran it again. Must have sent the wrong log file to you. Just in cast, I ran Adwcleaner and OTL again today - logs attached.

BTW, Firefox now opens and refreshes tabs without Avast alerts so I guess we're fixed! Thanks a million.

: Keep Java Updated :

WARNING: Java is the #1 exploited program at this time. The Department of Homeland Security recommends that computer users disable Java
See this article (http://www.forbes.com/sites/eliseackerman/2013/01/11/us-department-of-homeland-security-calls-on-computer-users-to-disable-java/) and this article (http://www.nbcnews.com/technology/technolog/us-warns-java-software-security-concerns-escalate-1B7938755).
I would recommend that you completely uninstall Java unless you need it to run an important software.
In that instance I would recommend that you disable Java in your browsers until you need it for that software and then enable it. (See How to diasble Java in your web browser (http://www.geekstogo.com/2600/how-to-disable-java-in-your-web-browser/) and How to unplug Java from the browser (http://krebsonsecurity.com/how-to-unplug-java-from-the-browser/))

Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

(http://img233.imageshack.us/img233/7729/mbamicontw5.gif) Malwarebytes (http://www.malwarebytes.org/mbam-download.php).

Update and run weekly to keep your system clean

Download and install FileHippo update checker (http://www.filehippo.com/updatechecker/) and run it monthly it will show you which programmes on your system need updating and give a download link

If you use on-line banking then as an added layer of protection install Trusteer Rapport  (http://www.trusteer.com/Products/Trusteer-Rapport-for-Online-Banking)

It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit To learn more about how to protect yourself while on the internet read our little guide  How did I get infected in the first place ?
