Thanks for the advise, however, the original post which I didn't make clear I guess was about the DOS window that installs Malwarebytes using the Chameleon interface. I want to stop Chameleon from using a DOS window to attempt to install, update and scan the computer. I used the MBam Chameleon screensaver in Chameleon to get Malwarebytes installed, updated and scan the computer to remove the trojan/virus and it worked. Now, randomly, the DOS interface (same program is initially used to install Malwarebytes using Chameleon Screensaver) for Chameleon pops up and attempts to run with msg: "Press any key to continue". I will address the others problems on the computer but want to stop Chameleon from opening a user uncommanded DOS window. Thanks for any help with this.
