desktop wallpaper changed to white

My winXP e-machine desktop wallpaper changed to white after an UNINTENDED malware detection program was installed and I cannot recover my original wallpaper. I've removed malware program and have run a number of spy/virus detection programs (Spyhunter, Spyware Doc, avast!, Ad-ware) hoping for a fix. Also, I've deleted entries in Properties>Desktop>Customized Desktop>Web, deleted wallpaper entries in the Register, and run System Restore. All to no avail. At startup my original wallpaper does appear for a few seconds before being replaced with the white background.

My HJT log is below and I would very much appreciate your help with this.
