Installing one of the leading IT security vendors is easy. I had already McAfee 2013 on my PC. Set The new version 2014 CD into the drive and off you go. Simply the prompts when they come then, follow. The old version is automatically uninstalled and installed the new software. Right in the middle then the PC software from McAfee servers (download) automatically loads itself again and that's it. Now my PC is again "safe" on the Internet on the go. Next year I will then buy the 2015er version.
