Title: "Malicious URL Blocked" message pops up constantly
Post by: darkwriter626 on January 15, 2013, 11:41:20 PM
I keep getting multiple "Malicious URL Blocked" messages on my computer. I did a full system scan with Avast and nothing was detected.
With Malwarebytes Anti-Malware, there have been two trojans which I can't seem to get rid of after several scans. Attached is the MBAM log.

I would greatly appreciate any assistance with this matter.
Thank you.

Hi,

Good job!

Run TDSSKiller again.  When you see \Device\Harddisk0\DR0 ( Rootkit.Boot.Pihar.c ) be sure to select Cure this time and attach the new log.

So, Combofix has been running for a little over 4 hours now and is stuck at "Completed Stage 49". Should I keep it going or restart it?
I'm going to keep it running for now until it finishes or until I hear otherwise from you.

Go ahead and restart it.  If you still have problems let me know.  :)

I'm still having the same problem after Stage 49... What should I do?

Boot to Safe Mode and try again. 

If you still have problems, run a new scan with OTL and post that.  :)

Hi and sorry for any delay.  I am in the middle of a home renovation.
-----------

Please download and run ERUNT (http://www.snapfiles.com/get/erunt.html) (Emergency Recovery Utility NT).  This program allows you to keep a complete backup of your registry and restore it when needed. The standard registry backup options that come with Windows back up most of the registry but not all of it. ERUNT however creates a complete backup set, including the Security hive and user related sections. ERUNT is easy to use and since it creates a full backup, there are no options or choices other than to select the location of the backup files. The backup set includes a small executable that will launch the registry restore if needed.  **Remember if you are using Windows Vista as your operating system right-click the executable and Run as Administrator.
----------

(http://i1224.photobucket.com/albums/ee380/jeffce74/OTL.jpg) Run OTL.exe
----------

Post the new OTL log and let me know how your system is running.  :)

Hi. That's ok. There's no rush.

The new OTL log is attached. My computer seems to be running faster than before and the "Malicious URL Blocked" messages have stopped appearing.

Hi,

Good to hear! 

(http://i1224.photobucket.com/albums/ee380/jeffce74/java.jpg)Please go to Start >> Control Panel >> Programs and Features >> uninstall all versions of Java.

There is an exploit in Java right now that does not have any fix for it, so for the time being I would not have Java on your system at all.
-------------

(http://i1224.photobucket.com/albums/ee380/jeffce74/mbam-3.jpg) Malwarebytes

Please open Malwarebytes, update it and then run a Quick Scan.  Save the log that is created for your next reply.

ESET Online Scanner

Go here (http://go.eset.com/us/online-scanner) to run an online scannner from ESET.  Windows Vista/Windows 7 users will need to right click on their Internet Explorer shortcut, and select Run as Administrator----------

Providing there are no other malware related problems...

IT APPEARS THAT YOUR LOGS ARE NOW CLEAN   SO LETS DO A COUPLE OF THINGS TO WRAP THIS UP!!

This infection appears to have been cleaned, but I can not give you any absolute guarantees.  As a precaution, I would go ahead and change all of your passwords as this is especially important after an infection.
----------

The following will implement some cleanup procedures as well as reset System Restore points:

Press the Windows key + R and this will open the Run box. Copy/paste the following text into the Run box as shown and click OK.
  Combofix /Uninstall
  (Note: There is a space between the ..X and the /U that needs to be there.)

(http://i1224.photobucket.com/albums/ee380/jeffce74/CF.jpg)
----------

Clean up with OTL:
----------

Any of the logs that you created for use in the forums or remaining tools that have not yet been removed can be deleted so they aren't cluttering up your desktop.
If you didn't already have it I would keep Malwarebytes AntiMalware though.


Here are some tips to reduce the potential for spyware infection in the future:

1. Internet Explorer.  Even if you don't use it as your main browser it should be kept up-to-date because that is the browser Windows uses for updates.
Make your Internet Explorer more secure
- This can be done by following these simple instructions:
2. FireFox.  If you use Firefox, I recommend installing the following add-ons to help make your Firefox browser more secure:
NoScript (http://"https://addons.mozilla.org/en-US/firefox/addon/noscript/")
AdBlock Plus (http://"https://addons.mozilla.org/en-US/firefox/addon/adblock-plus/?src=ss")

3. Enable Protected Mode in Internet Explorer.  This helps Windows Vista users stay more protected from attack by running Internet Explorer with restricted privileges as well as reducing the ability to write, alter or destroy data on your system or install malicious code.  To make sure this is running follow these steps:4. Use and update an anti-virus software - I can not overemphasize the need for you to use and update your anti-virus application on a regular basis.  With the ever increasing number of new variants of malware arriving on the scene daily, you become very susceptible to an attack without updated protection.

5. Firewall
Using a third-party firewall will allow you to give/deny access for applications that want to go online. Without a firewall your computer is susceptible to being hacked and taken over. Simply using a firewall in its default configuration can lower your risk greatly.  I would personally only recommend using one of the following two below:
Online Armor Free (http://download.cnet.com/Online-Armor-Free/3000-10435_4-10426782.html)
Agnitum Outpost Firewall Free (http://download.cnet.com/Agnitum-Outpost-Firewall-Free/3000-10435_4-10913746.html)

6. Make sure you keep your Windows OS currentWindows XP users can visit Windows update  (http://v4.windowsupdate.microsoft.com/en/default.asp)  regularly to download and install any critical updates and service packs. Windows Vista/7 users can open the Start menu > All Programs > Windows Update > Check for Updates (in left hand task pane) to update these systems.  Without these you are leaving the back door open.

7.   WOT   (http://www.mywot.com/) (Web of Trust) As "Googling" is such an integral part of internet life, this free browser add on warns you about risky websites that try to scam visitors, deliver malware or send spam. It is especially helpful when browsing or searching in unfamiliar territory. WOT's color-coded icons show you ratings for 21 million websites, helping you avoid the dangerous sites.  WOT has an add-on available for Firefox, Internet Explorer as well as Google Chrome.

8.Finally, I strongly recommend that you read How to Prevent Malware found here (http://"http://users.telenet.be/bluepatchy/miekiemoes/prevention.html") and also PC Safety and Security - What Do I Need? (http://www.techsupportforum.com/forums/f112/pc-safety-and-security-what-do-i-need-525915.html).
 
Please reply to this thread once more if you are satisfied so that we can mark the problem as resolved.
