Cmdow.A is a hacking tool. Though these programs are legitimate and useful tools when they are appropriately used, a hacker could take advantage of them in order to carry out malicious actions.
Cmdow.A is a command line utility that does not need to be installed.
Cmdow.A allows several actions to be carried out on existing windows. It can move, resize and rename them. It can also hide or unhide, disable or enable, minimimize, maximize or restore, close or end them.
Additionally, although Cmdow.A only functions on Windows 2003/XP/2000/NT, when it is used on autorun CDs, it will also function on Windows ME/98/95 computers.
Cmdow.A does not pose a risk by itself, but it can be used to prevent the user from viewing the windows which are being opened, due to programs that are being run or installed.
