Title: Malicious URL Blocked warning popping up everywhere
Post by: REDACTED on October 24, 2013, 06:18:40 AM
I need help fixing this issue.  It happens with Firefox only and just about on any action.  I have tried many things listed in forums and none of them have worked.  It looks like OTL will find and help remove the problem but I have no idea how to read the files it generates or tell it how to fix the problem.  If someone here can help me this would be great and much appreciated.

hi FauxZen,

Welcome to the forums.  [EDIT:]  Removed unnecessary information.   ;)

You'll need the support and advice of a certified malware removal expert.  To get that help, you'll need to run and attach the following four logs from these four programs:
You can get them here:  http://forum.avast.com/index.php?topic=53253.0 (http://forum.avast.com/index.php?topic=53253.0)

You can attach up to four logs on one post.  Once that is done, I will notify a malware expert.

Thank you for working on my problem.  See the attached report and screen shot.

Hmm something different

Lets see if I can locate it

Download and Install Combofix
 
Download ComboFix from one of the following locations:
Link 1  (http://download.bleepingcomputer.com/sUBs/ComboFix.exe)
Link 2 (http://www.forospyware.com/sUBs/ComboFix.exe)
 
VERY IMPORTANT !!! Save ComboFix.exe to your Desktop
 
* IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here  (http://forums.whatthetech.com/How_Disable_your_Security_Programs_t96260.html&pid=494216#entry494216)

(http://img.photobucket.com/albums/v706/ried7/NSIS_extraction.png)

Notes:
1. Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. Do not "re-run" Combofix. If you have a problem, reply back for further instructions.
3.  If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.


Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now

Could you now start firefox in safe mode https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode

Then let me know if the alerts still happen

Post by: REDACTED on October 25, 2013, 05:29:07 PM
no they are gone

OK pain in the butt time...  Start Firefox normally then disable all extensions add/ons
Re-enable the extensions one at a time until the alert re-appears then let me know which one it was so that I can kill it

It actually was not that hard as I have very few.  It is Video Player 1.3 1.3
Title: Re: Malicious URL Blocked warning popping up everywhere
Post by: REDACTED on October 25, 2013, 06:12:09 PM
I have simply removed the Video Player 1.3 1.3

Thanks I will now add that one to my long list :)

Is all well now ?
Title: Re: Malicious URL Blocked warning popping up everywhere
Post by: REDACTED on October 25, 2013, 07:42:33 PM
Yes, it appears so.  Thank you so much for your help and the trouble shooting tutorial through this exercise.

In that case methinks I will send you on your merry way :)

Subject to no further problems   :)

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems 

Now the best part of the day ----- Your log now appears clean  :thumbsup:

A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset  System Restore points:

Delete AswMBR from the desktop

Run AdwCleaner and select uninstall

Remove ComboFixRun OTL and hit the cleanup button.  It will remove all the programmes we have used plus itself. 

Clear Restore Points

Go Start > All Programmes > Accessories > System tools
Right click Disc Cleanup and select run as administrator
When it pops up at the first prompt select OK after it has done some calculations the tabs will appear
Select More Options tab
Press Sytem Restore and Shadow Copies Cleanup button

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

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 ?
