Hello,
Looks like McAfee let us Evaluate their Endpoint Security antivirus with no expiration. So you can get a Professional Antivirus for FREE, no licence key needed.
This kind of antivirus is usualy used in companies and managed from a console, in order to avoid the IT to manualy deploy de settings on each PC. The manager lets you deploy your settings remotely on all the endpoints installed in your company.
So you can just install that standalone version on your PC, it doesn’t need the manager to run. it is supposed to be an Evaluation but it as no expiration date and will work fo ever, the virus database will be updated as long as the antivirus version is supported.
You can download it straight from McAfee web site :
click ENDPOINT PROTECTION
Select the OS in the tab
Click Download button
Or for lazy people, from this direct link for Windows OS :
