There is a thread on the board discussing the removal of this PITA software. The thread is: http://www.bleepingcomputer.com/forums/t/66364/how-to-remove-deluxecommunications-uninstall-instructions/
After several hours of banging my head against the wall and trying to follow the instructions on this board (unsuccesfully, I might add) I came up with a way to beat this damn program.
The program installs itself in the c:\Program Files\DeluxeCommunications directory. There are 3 files in that directory, the primary file of concern is dxc.exe. I tried removing the registry key HKLM\Software\Microsoft\Windows\CurrentVersion\Run that starts up the dxc.exe but it immediately re-adds the registry entry.
What I had to do was to boot from my trusty Bart PE recovery CD. You can download Bart PE from http://www.nu2.nu/pebuilder/download/
. This program is used to build an ISO of a bootable Windows CD. There are a bunch of plugins but you will really only need a few default ones (command prompt, file manager).
After creating the Bart PE boot disk you need to reboot your computer off of the cdrom. Each machine is a bit different on how to boot from cd. Sometimes you have to go into your bios setting to change the boot order. I was fixing a Dell Latitude laptop and had to press F12 to select CD rom.
Once you boot up, there are a number of files that will need to be deleted. The spyware program constantly writes to the \windows\system32\hikmp.ini file what I believe is the installer file. You can run the command prompt and enter the following commands:
cd \program files\deluxecommunications
In order to trick out the program I created a new program in the deluxecommunications folder and write protected it. This way when it went to reinstall itself, the installer fails. In order to do this, enter the following commands while still in the c:\program files\deluxecommunications directory:
copy con dxc.exe
Press Ctrl-Z, this will create a file zero bytes in size.
Now to write protect it:
attrib +r +s +h dxc.exe
You can now quit out of Bart PE and restart your computer. When it boots up a DOS window will most likely appear which is the spyware loader trying to start dxc.exe but it will fail.
Now you can run the HijackThis to remove the registry entries or use Spybot Search & Destroy and/or AdAware which should be able to remove it from there.
