These potential suspicious files are antivirus drivers.

Your logs shows that your system is clean. If you have no further issues with your computer, then please proceed with the following housekeeping procedures outlined below.

Removing the tools we used:

Uninstall ComboFix

Remove Combofix now that we're done with it.
  • Please press the Windows Key and R on your keyboard. This will bring up the Run... command.
  • Now copy/paste this: ComboFix /Uninstall in the runbox and click OK. Note the space between the X and the /Uninstall, it needs to be there.

  • Click on Posted Image
  • You will be prompted to reboot your system. Please do so.

If you still have any tools or logs leftover on your computer you can go ahead and delete those off of your computer now.


There are a few things I recommend you to do once your computer is completely clean:

Updates for Windows - One of the essentials is to keep your computer updated with the latest operating system patches and security fixes. Windows Updates are constantly being revised to combat the newest hacks and threats, Microsoft releases security updates that help your computer from becoming vulnerable. It is best if you have these set to download automatically.

How to turn on Automatic Updates for Windows:

Updates for other installed software

A common attack method for hacking attempts and malware installs is to exploit known vulnerabilities in programs that are commonly installed on a person's computer. These vulnerabilities could allow a remote user or malware developer to install malware, keyloggers, and backdoors on to your computer without your knowledge or permission.
Some of the programs that are commonly exploited include Adobe Shockwave, Adobe Reader, Sun Java, Adobe Flash, and even Windows itself. Therefore it is crucial that everyone remain vigilant as to when a security vulnerability is found in our installed programs and to update it when a security update is released. Unfortunately, no one has the time to stay on top of these updates, which can happen frequently.

I highly recommend you to install Secunia Personal Software Inspector (PSI) that can be used to scan your computer for known vulnerable programs, provide information on the vulnerability, and provide a location to an update for the vulnerable program. A tutorial on how to use Secunia Personal Software Inspector (PSI) can be found here: Keep Software Updated with Secunia PSI.

Web Browsers - Picking the right internet browser is very important. You need to find one that suits your needs but that is also safe. All browsers listed below are far more secure than Internet Explorer, immune to almost all known browser hijackers, and also have the best built-in pop up blockers.

Although, if you prefer staying with Internet Explorer I highly recommend you do this :

Make Internet Explorer more secure:
  • Click Start > Run
  • Type Inetcpl.cpl & click OK
  • Click on the Security tab
  • Click Reset all zones to default level
  • Make sure the Internet Zone is selected & Click Custom level
  • In the ActiveX section, set the options Download signed and unsigned ActiveX controls to Prompt, and Initialize and Script ActiveX controls not marked as safe to Disable.
  • Next click OK, then Apply button and then OK to exit the Internet Properties page.

Tips to protect yourself against malware and reduce the potential for re-infection:

Now after all these steps, your PC will be more secure. However it is important to note that you can still get infected if you are not careful. One of the best security programs you can have is common sense. As malware gets more sophisticated, you need to be more wary. If you do get caught though and the above steps can't help prevent it, we will be here to help you out.

Stay secure and thank you for choosing GeeksToGo.

This original problem below has not returned and even though you did not know what is was, it seems to be fixed since I have not needed to reboot. Thanks again.


I've a problem with the PC sometimes just acting erratic after 6 to 8 hours use. Get DLL errors, images errors when opening any application. Also, error boxes are frequently blank with text invisible. Open file manager and there is missing text that appears and disappears erratically when mousing over. When I reboot all is good for another 6 to 8 hours.

Hi and sorry for the delay.

From provided logs it seems that those issues are not malware but rather hardware related. From problem description I would say your GPU is overheating or you have some bad RAM. Please do the following check when problems begins if possible:

  • Please download Speccy from here install and run it.
  • Wait a few minutes then click File menu then Save as Text file... and save report to your desktop.
  • Open that txt file in Notepad and find Operating System section and delete this line: Serial Number: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
  • Save it by clicking on File and then on Save.
  • Please attach that report in your next reply.

1. Download - Pre-Compiled Bootable ISO (.zip). If you prefer to use the USB version then use this link USB stick.
2. Unzip downloaded /memtest86+-4.20.iso.zip file.
3. Inside, you'll find /memtest86+-4.20.iso file.
4. Download, and install ImgBurn: http://www.imgburn.com/
5. Insert blank CD into your CD drive.
6. Open ImgBurn, and click on Write image file to disc
7. Click on Browse for a file... icon.
8. Locate memtest86+-4.20.iso file, and click Open button.
9. Click on ImgBurn green arrow to start burning bootable memtest86 CD:
10. Once the CD is created, boot from it, and memtest will automatically start to run. You may have to change the boot sequence in your BIOS to make it work right.

To change Boot Sequence in your BIOS
Reboot the system and at the first post screen (where it is counting up memory) start tapping the DEL button
This will enter you into the Bios\Cmos area.
Find the Advanced area and click Enter
Look for Boot Sequence or Boot Options and highlight that click Enter
Now highlight the first drive and follow the directions on the bottom of the screen on how to modify it and change it to CDrom.
Change the second drive to the C or Main Drive
Once that is done then click F10 to Save and Exit
You will prompted to enter Y to verify Save and Exit. Click Y and the system will now reboot with the new settings.

The running program will look something like this depending on the size and number of ram modules installed:

It's recommended to run 5-6 passes. Each pass contains very same 8 tests.

This will show the progress of the test. It can take a while. Be patient, or leave it running overnight.

The most important item here is the "errors" line. If you see ANY errors, even one, most likely, you have bad RAM.
