The log I attached may not be the most recent, in fact it may have been create during a scan in safe mode. But that is the same version I have been running. It crashes at atapi.sys every time.
Hmm this is weird as none of the other tools are even hinting at cidox
So lets run a scan with windows and the MBR inactive
Create an emergency repair USB drive:
Download Dr Web Live USB to your desktop
[]Connect a USB flash drive to the computer. Registering the plugging in event takes no more than 10 seconds.
[]Launch drwebliveusb.exe.
[*]The program will detect available USB-devices automatically and prompt you to choose the one you?d like to use as an emergency repair drive. You can format the device if you like (a warning will be displayed before you proceed with formatting). In order to read the License agreement, follow a corresponding link found in the program window (the page containing the license agreement text will be loaded in your default browser).

[]To create a bootable USB flash drive, press the Create Dr.Web LiveUSB button.
[]Files will be copied automatically.
[]Once the copying process is completed, press the Exit button to close the application.
[]Reboot the infected computer with the USB in the drive
[]Ensure that the first boot device is USB - If you are not sure about that then see this page for instructions
[]As loading starts, a dialogue window will prompt you to choose between the standard and safe modes.

[*]When it has completed

[]Select Open Report and copy to the USB
[]Once completed reboot to normal windows, and attach the report here
I ran the scanner a few times and it found around 50 or so items to fix and fixed them. I never did see the option to “open report” but I found the name of the log file in the help section and did a search for it. It’s too big so I split it up into 3 parts. There are 2 - 4 items that it repeatedly finds in between scans and booting into windows. Something about UserInit if I remember correctly.

Is Avast still alerting ?
Yes, Avast is still alerting
Could you do the following :
Go to > Control panel > administrative tools > computer management > storage > disc management
Then take a screen shot and post it here
Screenshot
Have you tried the Delete now option ?
It looks as though it may be alerting on the 10Gb EISA partition which is a restore partition
Yes, I have. It requests to schedule a boot scan and restart the computer, but it is not found during the boot scan and removed.
As it stands none of my tools have found it so I believe it is a false alarm on your recovery partition
If there was even a trace then TDSSKiller or DrWeb would have seen it.
Tick the do not alert again box
OK, will do. Thanks so much for the help! Happy holidays!!! 
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

Wait for the uninstall process to complete.
