I don't see anything obvious that would be causing a computer restart.

 

Maybe try downloading Hardware Monitor and make sure the computer is not possibly overheating or having some other hardware issue.

Please run the following.

 

Please download MiniToolBox save it to your desktop and run it.

Checkmark the following check-boxes:

  • Flush DNS
  • Report IE Proxy Settings
  • Reset IE Proxy Settings
  • Report FF Proxy Settings
  • Reset FF Proxy Settings
  • List content of Hosts
  • List IP configuration
  • List Winsock Entries
  • List last 10 Event Viewer log
  • List Installed Programs
  • List Devices
  • List Users, Partitions and Memory size.
  • List Minidump Files


Click Go and post the result (Result.txt). A copy of Result.txt will be saved in the same directory the tool is run.

Note: When using Reset FF Proxy Settings option Firefox should be closed.

Okay those logs look good - it was able to find and remove some junk.

Let's try another antivirus product and see if it can run and complete. 

 

If this cannot run and complete though then I'd have to believe you probably have some type of a hardware issue, possibly an overheating issue.

Sorry for the delay - lost track of your post.

 

 

At this time there are no more signs of an infection on your system.
However if you are still seeing any signs of an infection please let me know.

Let's go ahead and remove the tools and logs we've used during this process.

Most of the tools used are potentially dangerous to use unsupervised or if ran at the wrong time.
They are often updated daily so if you went to use them again in the future they would be outdated anyways.

The following procedures will implement some cleanup procedures to remove these tools.
It will also reset your System Restore by flushing out previous restore points and create a new restore point.
It will also remove all the backups our tools may have created.

Uninstall ComboFix (if used):

  • Turn off all active protection software including your antivirus.
  • Push the "Windows key" + "R" (between the "Ctrl" button and "Alt" Button)
  • Please copy and past the following into the box ComboFix /Uninstall and click OK.
  • Note the space between the X and the /Uninstall, it needs to be there.

Remove the rest of the tools used:

Please download
OTCleanIt
and save it to your Desktop. This tool will remove all the tools we used to clean your pc.

  • Double-click OTCleanIt.exe.
  • Click the CleanUp! button.
  • Select Yes when the "Begin cleanup Process?" prompt appears.
  • If you are prompted to Reboot during the cleanup, select Yes.
  • The tool will delete itself once it finishes, if not go ahead and delete it by yourself.
  • If asked to restart the computer, please do so


Note:

If you receive a warning from your firewall or other security programs regarding
OTCleanIt
attempting to contact the internet, please allow it to do so.


AdwCleaner Removal:
  • Double click on AdwCleaner.exe to run the tool.
  • Click on Uninstall
  • Confirm with Yes

ESET antivirus Removal:
  • This tool can be uninstalled via the Control Panel, Programs, Uninstall


If there are any other left over Folders, Files, Logs then you can delete them on your own.

Please visit the following link to see how to delete old System Restore Points. Please delete all of them and create a new one at this time.

Please read the following articles which will help you to better understand how the computer may have become infected as well as how to help prevent future infections. Nothing is 100% bulletproof but with a little bit of education you can certainly swing things in your favor.


If you're not currently using Malwarebytes PRO then you may want to consider purchasing the product which can also help greatly reduce the risk of a future infection.
