Well, its not breaking now, which is a relief.
It will take a while to regain confidence and straighten all the settings which have changed since the old pATA drive was in use, but I think I'll get there.

I also have several boot CDs and flash drives for various Linux systems, some of which I have used many times in the past successfully, but none of them work now.

But that is a puzzle for another forum.
So thank you so much for all your help and perseverance , and I think we can leave it at that.

Dave

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:

Run OTL
  • Under the Custom Scans/Fixes box at the bottom, paste in the following
    Quote
    :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
  • Go to control panel
  • Select folder options (Appearance > Folder options in category view)
  • 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Your Java is out of date.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:

Cleaned up OK.
Java updated.
Installed Malwarebytes.
Installed FileHippo - that's handy, especially when the system was recovered from an old drive.
Updated lots of things.
Malwarewarebytes scan - clean.

There's still lots of things every reboot on the Event Log to do with Peer Networking, but I will eventually get that sorted.
Thanks again.

Event Log from latest start attached.
The curious thing is my network is working fine, except for one wrinkle.
When Truecrypt "virtual drives" are mounted and made network shares, after the next reboot they are reset to Not Shared.
A feature "refresh network shares" would be good, like happens with removable hard drives that aren't attached at startup.

OK could you do the following :

Copy C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking\idstore.sst to your desktop
Delete C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking\idstore.sst

Reboot

If that does not resolve it then do the following :

Go to Control Panel\All Control Panel Items\HomeGroup
Select Trouble shoot and follow the prompts

Together they should cure the problem

I've done that already.
I was expecting the file to be rebuilt using idstore.sst.new , bit it is missing (not hidden).

The troubleshooter first checks network diagnostics and finds PNRPsvc was not running and couldn't be started.
It then goes on to Homegroup diagnostics, and finds the same thing.
No other problems identified.

I have downloaded PNRP.txt (.reg) from https://avnzfa.bay.livefilestore.com/y1pOKvfZXsDi-RaNYFFHRfNE6cY2d6jHkipSJ7iU6WdNI-wqc2NPIJvjDXWHJQLy8h5O6uekU-1xwyfQ8F2hsSw8g/PRNP.txt?download&psid=1
linked from https://skydrive.live.com/?cid=6df3bca839e981ef&id=6DF3BCA839E981EF!134
but I am reluctant to apply that because I am not sure that is my problem.

Meanwhile if I right-click on the target folder on virtual drive and click Share With > Homegroup read/write
it gets around the problem, although it is not automatic.
