Hello, I've been all day online and thought that no more problems were present. But a late evening scan with avast internet security showed a appn.dll and another thing, all in system32. However, there was no avast popup, so no consrv.dll re-creation, and no pings. Then I left for home, next Monday I can rescan and send a log.

This morning redid another scan with avast internet security, after rebooting a couple of times, and nothing was found.
I have uninstalled it, and did the OTL scan.
I am going to reinstall avast and keeping fingers crossed.
Thank you essexboy!

Hello essexboy, no signs of infection in nearly two whole days of work. I believe it's clean now!

Subject to no further problems   :)

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:

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.

Your Java is out of date. Older versions have vulnerabilities that malware can use to infect your system.
Please follow these steps to remove older version of Java components and upgrade the application.

 Upgrading Java:
  • Go to this site  and click Do I have Java
  • It will check your current version and then offer to update to the latest version
SPRING CLEAN

To manually create a new Restore Point
 
  • Go to Control Panel and select System
  • Select System
  • On the left select System Protection and accept the warning if you get one
  • Select System Protection Tab
  • Select Create at the bottom
  • Type in a name i.e. Clean
  • Select Create
Now we can purge the infected ones
  • GoStart > All programs > Accessories > system tools
  • Right click Disc cleanup and select run as administrator
  • Select Your main drive and accept the warning if you get one
  • For a few moments the system will make some calculations
  • Select the More Options tab
  • In the System Restore and Shadow Backups select Clean up
  • Select Delete on the pop up
  • Select OK
  • Select Delete
Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

Malwarebytes.  Update and run weekly to keep your system clean

Download and install FileHippo update checker and run it monthly it will show you which programmes on your system need updating and give a download link

It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit
To learn more about how to protect yourself while on the internet read our little guide  How did I get infected in the first place ?

Keep safe  :wave:

Thank you essexboy, wonderful job and excellent instructions!

No problems at all after several reboots and rescans with avast internet security and malwarebytes. A minor problem was that I goofily attempted to uninstall combofix twice (I don't know why!), and the second time I got a BSOD. But the PC is OK now.

After manually looking around here and there, there are a couple of things:

* there is one folder in the C root named "32788R22FWJFW", which I believe contains some antivirus tool (ERUNT.3XE and other similarly named programs) I attempted to install and run before coming here: scanning tells no menace detected, I think I can delete it right now.
* there is a program called "conhost(121).exe" in windows\system32, which I believe too has been left back during a virus removal attempt by some tool.

Yes you can delete those as they are just backups and will do no harm
