Neither Nilaunch.exe nor shicoxp.exe had any detections. the numbers were something like 0/42 and 0/23.
I DID remove the viewpoint media player.
Avira is still installed. If you go back to my first post (something like 2 weeks ago!), I believe that I did indicate that I used it to eliminate the virus initially. It is still functioning, but only when I start it. That is, it is not constantly monitoring anything. It is the free version and I do scans once a week or so.
Going back to ComboFix, even though it did not complete, I DID find a log file in its directory, mbr.log:
Stealth MBR rootkit/Mebroot/Sinowal/TDL4 detector 0.4.2 by Gmer,
http://www.gmer.net
Windows 5.1.2600 Disk: SEAGATE_ rev.0003 -> Harddisk0\DR0 -> \Device\Scsi\adpu160m1Port2Path0Target2Lun0
device: opened successfully
user: MBR read successfully
kernel: MBR read successfully
user != kernel MBR !!!
error: Read The request could not be performed because of an I/O device error.
I noticed that the I/O error corresponds to a SCSI error in the event logs. I looked that up online, decoded the error and found this:
[xxxxx0ce] Scatter/gather limit exceeded
An I/O request packet from the system contained a Scatter/Gather element list
that contained more elements than are supported by the miniport.
Scatter/Gather is a list of data segments that define the entire data transfer.
Scatter/Gather is a means to improve total data throughput. This error
might be caused by a component external to the miniport driver, such as
the operating system or an ASPI application.
thanks again!
