Please right click the combofix icon and select Rename. Rename the file to Random, then run it like that.

I tried this also... it did not work.. same issue.

• Push
  
• OTL may ask to reboot the machine. Please do so if asked.
  
• Click the OK button.
  
• A report will open. Copy and Paste that report in your next reply.

I ran the OTL scan successfully. I have attached the report below.
I have not noticed any "Intrusion attempt blocked" messages from Norton. I still see 2 iexplorer.exe running in the background even though I'm only using one tab (You had mentioned this may be normal though)... It is an improvement from before, as I would have as many as 5 iexplorer.exe running in the background. My google searches do not redirect as they did before.

When we initially started this process, I was unsuccesful at running the DDS file and recently, Combofix. Should I be concerned about this? Are you able to tell if something is impeding these from running?

Thanks for your help.
Here's the OTL report:

Registry entries deleted on Reboot...

Hi, the fact that both dds anc combofix do not run, indicate most likely tht one component both scanners use does not want to run correctly on your computer. This is not cause for worry.

Your version of Java is out of date. Older versions have vulnerabilities that malicious sites can use to exploit and infect your system.

• Download the latest version of Java Runtime Environment (JRE) Version 6.
  
• Look for "JDK 6 Update 26 (JDK or JRE).
  
• Click the "Download JRE" button at the right.
  
• Read the License Agreement, and then check the box that says: "Accept License Agreement".
  
  • Select "Windows x86 Offline" and click on jre-6u26-windows-i586.exe
• Save it to your desktop
  
• Close any programs you may have running - especially your web browser.
  
• Uninstall all older versions of Java (any item with Java Runtime Environment, JRE or J2SE in the name).
  
• Reboot your computer once all Java components are removed.
  
• Install the newest version by double clicking (run as Administrator for Windows Vista/Seven) the downloaded file.

MALWAREBYTES ANTIMALWARE
-------------------------------------------
Please download Malwarebytes Anti-Malware and save it to your desktop.

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.

• Make sure you are connected to the Internet.
  
• Double-click on mbam-setup.exe to install the application.
  
• When the installation begins, follow the prompts and do not make any changes to default settings.
  
• When installation has finished, make sure you leave both of these checked:
  • Update Malwarebytes' Anti-Malware
    
  • Launch Malwarebytes' Anti-Malware
  
  
• Then click Finish.

MBAM will automatically start and you will be asked to update the program before performing a scan.

• If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  
• If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.

On the Scanner tab:

• Make sure the "Perform Full Scan" option is selected.
  
• Then click on the Scan button.
  
• If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  
• The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  
• When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  
• Click OK to close the message box and continue with the removal process.

Back at the main Scanner screen:

• Click on the Show Results button to see a list of any malware that was found.
  
• Make sure that everything is checked, and click Remove Selected.
  
• When removal is completed, a log report will open in Notepad.
  
• The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  
• Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  
• Exit MBAM when done.

Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

ALL CLEAN
--------------
Your machine appears to be clean, please take the time to read below on how to secure the machine and take the necessary steps to keep it clean

Please do the following to remove the remaining programs from your PC:

• Delete the tools used during the disinfection:
  • Click start > run and type combofix /uninstall, press enter. This will remove Combofix from your computer.
    
  • Rerun OTL and click the Cleanup button. Allow a reboot.

Please read these advices, in order to prevent reinfecting your PC:

• Install and update the following programs regularly:
  • an outbound firewall. If you are connected to the internet through a router, you are already behind a hardware firewall and as such you do not need an extra software firewall.
    A comprehensive tutorial and a list of possible firewalls can be found here.
    
  • an AntiVirus Software
    It is imperative that you update your AntiVirus Software on regular basis.If you do not update your AntiVirus Software then it will not be able to catch the latest threats.
    
  • an Anti-Spyware program
    Malware Byte's Anti Malware is an excellent Anti-Spyware scanner. It's scan times are usually under ten minutes, and has excellent detection and removal rates.
    SUPERAntiSpyware is another good scanner with high detection and removal rates.
    Both programs are free for non commercial home use but provide a resident and do not nag if you purchase the paid versions.
    
  • Spyware Blaster
    A tutorial for Spywareblaster can be found here. If you wish, the commercial version provides automatic updating.
  
  
• Keep Windows (and your other Microsoft software) up to date!
  I cannot stress how important this is enough. Often holes are found in Internet Explorer or Windows itself that require patching. Sometimes these holes will allow an attacker unrestricted access to your computer.
  Therefore, please, visit the Microsoft Update Website and follow the on screen instructions to setup Microsoft Update. Also follow the instructions to update your system. Please REBOOT and repeat this process until there are no more updates to install!!
  
• Keep your other software up to date as well
  Software does not need to be made by Microsoft to be insecure. You can use the Secunia Online Software occasionally to help you check for out of date software on yourmachine.
  
• Stay up to date!
  The MOST IMPORTANT part of any security setup is keeping the software up to date. Malware writers release new variants every single day. If your software updates don't keep up, then the malware will always be one step ahead. Not a good thing.

Thanks Elise for your help!!

Just one more question... I have noticed something that has just recently started happening (last day or 2)...
When Im using Internet Explorer, I have the pop-up blocker on... If I am half way down on a certain page and click on a link, the pop-up is blocked (normal). So I remporarily allow pop-ups from that site... and the link opens in another window (normal). When I do that, the original page I was viewing refreshes... since I wa sviewing it at the half way mark, I loose my place on the page as it takes me back all the way to the top. Its really annoying... I dont remember this happening before. Should I be concerned about this?

Thanks

No, tbh, this is one of the reasons why I don't use Internet Explorer. This is nothing to worry about. If it did not do this before, you could try cleaning out the cache, or even try to reset internet explorer settings, but there is no reason to be worried about this behavior.

Please let me know if this answers your question.

Yes it did answer my question. Thanks for your time, Elise.

It appears that this issue is resolved, therefore I am closing the topic. If that is not the case and you need or wish to continue with this topic, please send me or any Moderator a Personal Message (PM) that you would like this topic re-opened.
