Hello, and welcome to Malware Removal Forums.
My name is Matt and I will be assisting you with your malware issues.
Please be patient as I need some time to review your HijackThis log and I will post back recommendations for repairs.
As I am still on training, everything that I post to you, must be checked by a Teacher. Thus, there may be a tiny bit of a delay between posts, but it shouldn't be too long.
  • Whatever repairs we make, are for fixing your computer problems only and by no means should be used on another computer.
  • Continue to respond to this thread until I give you the All Clean! If you have any questions or you're stuck in there please reply it to me. I will try my best to help you! Not having symptoms of malware doesn't mean that you are clean!
  • Please do not carry out tasks on your own before I reply as this will only complicate things and may mean that my instructions are useless or dangerous!
  • Please bookmark or favourite this page. In case you need it as reference or etc.
Hi

Download SDFix and save it to your Desktop.

Double click SDFix.exe and it will extract the files to %systemdrive%
(Drive that contains the Windows Directory, typically C:\SDFix)

Please then reboot your computer in Safe Mode by doing the following :
  • Restart your computer
  • After hearing your computer beep once during startup, but before the Windows icon appears, tap the F8 key continually;
  • Instead of Windows loading as normal, the Advanced Options Menu should appear;
  • Select the first option, to run Windows in Safe Mode, then press Enter.
  • Choose your usual account.
  • Open the extracted SDFix folder and double click RunThis.bat to start the script.
  • Type Y to begin the cleanup process.
  • It will remove any Trojan Services and Registry Entries that it finds then prompt you to press any key to Reboot.
  • Press any Key and it will restart the PC.
  • When the PC restarts the Fixtool will run again and complete the removal process then display Finished, press any key to end the script and load your desktop icons.
  • Once the desktop icons load the SDFix report will open on screen and also save into the SDFix folder as Report.txt
    (Report.txt will also be copied to Clipboard ready for posting back on the forum).
  • Finally paste the contents of the Report.txt back on the forum with a new HijackThis log

Hi
Can I see the Malwarebytes' log please? It is located here:
C:\Documents and Settings\<User name>\Application Data\Malwarebytes\Malwarebytes' Anti-Malware\Logs\mbam-log-date (time).txt
Hi
Thanks. That cleaned up some stuff!

Let's clear out the programs we've been using to clean up your computer, they are not suitable for general malware removal and could cause damage if used inappropriately.
  • Double click OTMoveIt2.exe to launch it.
  • Click on the CleanUp! button.
  • OTMoveIt will download a list from the Internet, if your firewall or other defensive programs alerts you, allow it access.
  • You will be prompted to allow the clean up procedure, click Yes
  • When finished exit out of OTMoveIt2
  • Now delete OTMoveIt2.exe (if still present)


Now that you are clean, please follow these simple steps in order to keep your computer clean and secure:

  1. Disable and Enable System Restore. - If you are using Windows ME/XP/Vista then you should disable and re-enable system restore to make sure there are no infected files found in a restore point.

    Reset System Restore.
    Now you should disable System restore to purge any infected files and then re-enable it,

    On the Desktop, right-click My Computer.
    Click Properties.
    Click the System Restore tab.
    Check Turn off System Restore.
    Click Apply, and then click OK.
    Restart your computer

    Turn ON System Restore

    On the Desktop, right-click My Computer.
    Click Properties.
    Click the System Restore tab.
    Un-Check Turn off System Restore.
    Click Apply, and then click OK.
  2. Make your Internet Explorer more secure - This can be done by following these simple instructions:
    1. From within Internet Explorer click on the Tools menu and then click on Options.
    2. Click once on the Security tab
    3. Click once on the Internet icon so it becomes highlighted.
    4. Click once on the Custom Level button.
      1. Change the Download signed ActiveX controls to Prompt
      2. Change the Download unsigned ActiveX controls to Disable
      3. Change the Initialise and script ActiveX controls not marked as safe to Disable
      4. Change the Installation of desktop items to Prompt
      5. Change the Launching programs and files in an IFRAME to Prompt
      6. Change the Navigate sub-frames across different domains to Prompt
      7. When all these settings have been made, click on the OK button.
      8. If it prompts you as to whether or not you want to save the settings, press the Yes button.
    5. Next press the Apply button and then the OK to exit the Internet Properties page.
  3. Update your Anti Virus Software - It is imperitive that you update your Anti virus software at least once a week (Even more if you wish). If you do not update your anti virus software then it will not be able to catch any of the new variants that may come out.
  4. Use a Firewall - I can not stress how important it is that you use a Firewall on your computer. 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. For an article on Firewalls and a listing of some available ones see the link below:
    Computer Safety On line - Software Firewalls
  5. Visit Microsoft's Windows Update Site Frequently - It is important that you visit http://www.windowsupdate.com regularly. This will ensure your computer has always the latest security updates available installed on your computer. If there are new updates to install, install them immediately, reboot your computer, and revisit the site until there are no more critical updates.
  6. Install WinPatrol - Download and install Winpatrol by BillP Studios.
    This program can monitor what software start with Windows. You can delay startup for some programs and stop malicious programs from starting up. It can also view some hidden files.
    Download it from here
  7. Install Spybot - Search and Destroy - Download and install Spybot - Search and Destroy with its TeaTimer option.
    This will provide real-time spyware & hijacker protection on your computer alongside your virus protection. You should also scan your computer with program on a regular basis just as you would an anti virus software. A tutorial on installing & using this product can be found here:
    Instructions for - Spybot S & D
  8. Install SpywareBlaster - SpywareBlaster will added a large list of programs and sites into your Internet Explorer settings that will protect you from running and downloading known malicious programs. A article on anti-malware products with links for this program and others can be found here:
    Computer Safety on line - Anti-Malware
  9. Install ThreatFire - Download and install ThreatFire. This program defends against malware by detecting certain malicious behaviours. It is configured "out-of-the-box" and acts as a complement to your Antivirus software. It can be downloaded here:
    PC Tools ThreatFire
  10. Update all these programs regularly - Make sure you update all the programs I have listed regularly. Without regular updates you WILL NOT be protected when new malicious programs are released.
Follow this list and your potential for being infected again will reduce dramatically.
No problem, glad I could help :)
