No it did not stop the alerts. However, after the reboot that was required a RootKit Found message window displayed “MBR:\.PHYSICAL DRIVE0\Boot MBR:Cidox-D [Rtk]”. On prior occasions I have seen this message and have tried deleting as the pop up window suggests. I did not do so this time.

Here is the log you requested.

For EssexBoy, this is what I came up with for the fixlist:

Somehow I did not feel it would

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

10

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

11

Does the blue screen reference a driver ?

Are the alerts still present

12

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.

13

Here is the BlueScreen dump file.

14

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

15

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

16

Here you go. No change in the problem.

17

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

18

Here are the FRST & Shortcut text files you requested.

19

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
