While you can install computer software from a CD or DVD onto the local hard disk, you cannot normally reverse this process. Installation typically is more than copying several files into several places, and it is those "other tasks" that cannot easily be reversed. You can uninstall the software through the means provided and re-install it later, provided you still have the installer and all license keys and/or serial numbers. Manually removing portions of some unwanted software by removing or deleting files from the hard disk is NOT RECOMMENDED. At best, the application in question will no longer work. At worst, other applications and components may also suffer from this move. The "other tasks" that are typically done during software installation, in addition to the copying of files and data, include the registration of various aspects of the installed software within the system. Microsoft Word, for example, registeres the .doc file extensions such that you can double-click a .doc file, and Word opens. Many other, more complex, registration steps are typically implemented by modern software.

Generally, you can't write (meaning delete also) to a CD unless it's rewritable, so I would move the data to a temporary device like a USB stick that doesn't have anything important on it. Scan the USB stick with an antivirus program to make sure the virus is deleted and make another CD.
