I followed NDProxy to here: NDPROXY Overview (Windows Drivers)
and read the advisory referenced on that page (advisory does not apply to Win7).

That took me to a few places, which sort of indicated malware. Sort of because the initial reference states with Vista and above are not affected....

Anyway, it wouldn't hurt to scan your system

Download: Farbar Recovery Scan Tool Download
Select the version that applies to your system: 64-bit

Save it to your Desktop.

Double-click the downloaded file to run it.
When the tool opens, click Yes to the disclaimer.
Also check the Addition.txt, if not already checked.

Press the Scan button.

When done, the tool makes a log, FRST.txt, on the Desktop.

Please provide the FRST.txt in your reply.

It also creates another log: Addition.txt
Also post the Addition.txt in your reply.

I would like to say firstly thanks to all the help here, it really is appreciated.

So some additional weirdness. Tried to start my machine tonight and the monitor would not even display a picture (no signal). Tried a few reboots and nothing. Eventually resorted to using one of the DVI outputs rather than the mini HDMI output on the card and machine showed picture and booted, BUT still with black screen pause of about 2 minutes. Not sure this is absolutely relevant or a red herring.

So I have tried some tests (but not all) as suggested.

Firstly, my SSD drive ticks all the boxes. Plenty of life left, passed stress tests and is at the latest firmware version. (Intel tools)

Tried the video card test to push the card - Temp stopped at 89C and in a real hard push with all settings ticked as advised, got weird flashes of text now and again across the bottom and sides of screen and could not see the text int he top left telling me what was going on.

I have run the FARBAR scan and results are attached. I will do the other recommendations later if that's OK.

Once again, thanks so much for your kind support.

Hi There again

Here is my log - incidentally the scan picked up one threat for which I have not taken any action on:

TDSS File System
Physical Drive: \Device\Harddisk1\DR1
Suspicious Object, Medium Risk

Thanks again for your help.

The log says that you have a TDSS file system on that drive, that is not a good thing. It's not on drive 0 so that is a good thing.

Run TDSSKiller again and when you get to the take action window, please post a screenshot.

Take a look at the possible actions (delete, cure, quarantine?).

I think there might be a submit to TotalVirus, not sure what the screen says though.

This is what TDSS is, also called Alureon, could be part of a botnet stealing info. It's not good on any drive, hopefully your OS isn't on drive 1.

Thanks Gary, that's pretty much why I asked bluejohnny to run TDSSKiller again. That was 5 hours ago, but we're in different time zones, so we'll have to wait for the Earth to spin a little bit.

Normally you would try to cure, then quarantine, then delete malware. A rootkit is a different beast.
I wanted to see what the utility presented before advising a course of action.

Hi Guys - I re-ran TDSSKiller and this time it has reported no Threats Found. I saw the last thing it scanned was HardDisk1\DR1\Partition1 but no threats were found. I restarted but my black screen still persists.

If I am free of Malware, I am wondering whether Windows is waiting for some process to time out. I read the blog that was recommended, The cause of very slow logins, but to be honest I think the things that were being written about there, I don't possess the skills to do. :-(

I also noticed tonight that on the reboot, the arrow on the black screen changed to a rotating circle as if waiting form some process to finish.

Is there anything else you can advise I check please?

Thanks for your help.

Post the TDSSKiller log from the last run. These things are tricky - if you didn't take action the first time TDSSKiller ran, then it's still there. the log will tell more.

There's a good chance that after looking at the log, I'll ask you to run TDSSKiller again!
Once the TDSS file system is resolved, there are a number of malware scans to run. Many malware 'invite' their friends so a few scanners are good practice.

I'm wondering if you forgot to tick Detect TDLFS file system (you caught the mistake the very first time you ran TDSSKiller and restarted it with the parameter marked.)

I can't tell if disk 1 is external or internal, if it's the same disk as before or what. You're the eyes on that side of the monitor (your System Specs don't say if the 1 TB drive is internal or external, so I'm assuming that the 160 GD SSD is your boot, the 1TB drive is an internal drive and that it is the same drive as before.

Please post information about your drives having this information also makes it easier to a discuss course of action.
See: Disk Management - Post a Screen Capture Image
Post# 12 provides additional information on how to provide the most useful screenshot.

In addition to that addendum, please make sure that the Status column shows everything in between the parenthesis (Boot, Page file....)

Thanks
