Since the advent of various computer programs and software, the concept of malware or viruses has become perhaps the prime concern of programmers and users as a whole, be it at home or any enterprise. Software designers have designed a number of various highly efficient anti-viruses, which are more like vaccines, to prevent virus attacks and other malware functions to a system.

Issues while uninstalling McAfee Products:
However, there is one major drawback of using McAfee products. A user faces problems in completely removing McAfee products if he has to uninstall one. Uninstalling the program from “Add or Remove Programs” in the Control Panel, or deleting the installed files from the directory location does not remove McAfee products completely. This hinders the future installation of similar programs when the user opts to install a new one. The system indicates that the previous McAfee product is still installed and it’s unable to carry out the installation of a similar new program.

Removing process:
McAfee itself provides a solution to this problem. The McAfee Consumer Products Removal (MCPR) Tool, launched by McAfee completely uninstalls any McAfee product installed in the system. This tool is a simple “.exe” file, which on installation searches for any installed McAfee products on your system.

The procedure for completely removing a McAfee product is described below:
1. Download McAfee Consumer Products Removal (MCPR) Tool.
2. Press the downloaded file to install it to your system. Windows Vista users need to right click on the downloaded file and then select to “Run as Administrator”. Confirm any messages appearing to continue.
3. Once installed, the MCPR takes charge of its process of removing the McAfee products installed in your system.
4. When all the McAfee products are removed completely, i.e., the removal process is finished, a message declaring “Cleaning Successful” appears. Restart your system to finish removing McAfee products completely from your system.
