16 bit MS-Dos subsystem error after running scans

I ran SuperAntiSpyware, Malwarebytes and ComboFix in that order. I think the error is related to something ComboFix did but I'm not sure. I get a window that pops up on non-admin accounts that says:

"C:\DOCUME~\username\LOCALS~\Temp\pxslomem.com
C:\DOCUME~\username\LOCALS~\Temp\, a temporary file needed for initialization could not be created or could not be written to. Make sure that the directory path exists, and disk space is available. Choose 'Close' to terminate the application"

If a make the user a power user or admin they don't get the error. Unfortunately cannot remove read-only permissions from the %temp% directory. I have also tried replacing Config.nt, Autoexec.nt and Command.com with the originals from the XP CD.

 

Logs:


ComboFix 10-07-27.05 - PCSSadmin 07/28/2010 14:19:01.2.2 - x86

 

Sorry about that

 

I re-imaged the PC after running all the suggested apps and then ran combofix on the base image and deployed the PC, that is when I noticed all non-admins who received this PC image were getting the error. I did not install and run SAS, MBAM or MGTools on the 'clean' image

 

I believe it is an issue caused by Combofix, if need be I will post to software
