ComboFix got past step 50 then started deleteting some files and then I got a blue screen. The think the message stated that mbr.sys driver was halted with items in que. I used BlueScreenView to View the following message.

Did the sytem reboot OK ?

Is there a log at c:\combofix.txt

system · 2015-04-26T13:28:05.000Z

Yes the system rebooted OK but blue screened again later. I have attached the Combofix.txt file.

essexboy · 2015-04-26T13:46:07.000Z

Does the blue screen reference a driver ?

Are the alerts still present

system · 2015-04-26T14:16:25.000Z

Yes the alarts are still occuring. I attached the blue screen crash list. I’m not very familar with the BlueScreen program so let me know if I provided the wronge info.

system · 2015-04-26T14:31:33.000Z

Here is the BlueScreen dump file.

system · 2015-04-26T15:01:52.000Z

Just to be clear, the Blue screen data I have sent you pertains to only the most recent crash. There are 41 crashes listed.

essexboy · 2015-04-26T15:52:18.000Z

Could you re-run combofix please, allow it to update if it asks

system · 2015-04-26T17:38:06.000Z

Here you go. No change in the problem.

essexboy · 2015-04-26T18:39:34.000Z

Could you download a fresh copy of FRST please, run the scan again but this time also tick shortcut txt
Please download Farbar Recovery Scan Tool and save it to your Desktop.

Then attach all 3 logs

system · 2015-04-27T04:40:41.000Z

Here are the FRST & Shortcut text files you requested.

system · 2015-04-27T05:43:25.000Z

I’m a little confused as to what file you wanted. Here are two files from FRST in my documents directory and one from the Desk Top directory. Is this what you requested?

I am unable to locate the trigger yet

I preformed the scans and am ready to provide the log files. However, I am not familar with file sharing sites and don’t understand where you want me to upload them to. Also, do you want the zip, xml & htm versions of the virusinfo_secure files?

system · 2015-04-27T16:22:57.000Z

I think I figured out file sharing. Let me know if this works for you.
