I see you have allready run combofix - could you post that log please

thank you

When you run combofix this time allow it to update if it asks

  1. Close any open browsers.
  2. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
  3. Open notepad and copy/paste the text in the quotebox below into it:
File:: c:\windows\system32\drivers\sltjoqeb.sys c:\windows\system32\drivers\gyhktenb.sys c:\windows\system32\drivers\rxgwfabh.sys

Driver::
gyhktenb
rxgwfabh

Save this as CFScript.txt, in the same location as ComboFix.exe

Refering to the picture above, drag CFScript into ComboFix.exeWhen finished, it shall produce a log for you at C:\ComboFix.txt which I will require in your next reply.

Subject to no further problems :slight_smile:

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems

Now the best part of the day ----- Your log now appears clean :thumbsup:
.
A good workman always cleans up after himself so…The following will implement some cleanup procedures as well as reset System Restore points:
.
Run OTL
[*]Under the Custom Scans/Fixes box at the bottom, paste in the following

:Commands [resethosts] [emptytemp] [Reboot]

[*]Then click the Run Fix button at the top
[*]Let the program run unhindered, reboot the PC when it is done

.
Remove ComboFix
.

[*]Hold down the Windows key + R on your keyboard. This will display the Run dialogue box
[*]In the Run box, type in ComboFix /Uninstall (Notice the space between the “x” and “/”) then click OK
.

.
[]Follow the prompts on the screen
[]A message should appear confirming that ComboFix was uninstalled

.
Run OTL and hit the cleanup button. It will remove all the programmes we have used plus itself.
.
We will now confirm that your hidden files are set to that, as some of the tools I use will change that

[*]Click Start.
[*]Open My Computer.
[*]Select the Tools menu and click Folder Options.
[*]Select the View Tab.
[*]Under the Hidden files and folders heading select Do not show hidden files and folders.
[]Click Yes to confirm.
[]Click OK.
