System Requirements and Installation
McAfee Antivirus runs on 32-bit and 64-bit editions of Vista and Windows 7. It can be installed to XP 32-bit but not to 64-bit edition. The supported browsers of SiteAdvisor are Firefox and Internet Explorer. McAfee products do not support multi-touch screens but will continue to protect the computer.
Installing McAfee is a breeze since there is no need to restart the computer even if you chose to install the personal firewall. Like the previous versions of McAfee AntiVirus Plus, the end-user can customize the installation. You can select to install only the virus protection without installing shredder, QuickClean, personal firewall, and SiteAdvisor.
The only time you’ll have to restart the computer is when the built-in updater downloaded and installed program updates. Existing customers of McAfee can upgrade to the 2011 edition as long as the subscription is active. If you are going to upgrade the computer from earlier versions of Windows, it is recommended to update to the new version of McAfee that provides support to newer operating systems such as Vista and Windows 7. Only upgrade the operating system with McAfee antivirus after installing the latest version of the antivirus program.
If you opted to install McAfee SiteAdvisor, an option to enable secure search will be displayed. Secure search is not required to use because the product will continue to check the status of sites that you will be visiting. Secure search only integrates a third-party search provider.
The installation of McAfee AV 2011 will add mcagent.exe in the startup item of Windows. It will also install a service (McSvHost.exe) that is integrated to many components of the antivirus program. Other services that you will notice are mcods.exe, mcshield.exe, mfefire.exe, and mfevtps.exe. Those are required to be running to enjoy full protection offered by McAfee AntiVirus Plus 2011.
