Yes, safe to uninstall them. Just make sure you have some antiviral software running. Windows Defender comes with Win 10 and is free.  There are other free and paid apps too. Go to McAfee's site and find their removal tool. Use that to uninstall McAfee fully so there are no remnants left over.
I have macafee virus guard that it came with my laptop. The subscription must be ended now because i have bought this laptop around 2 and 1/2 years ago. In 2012 december.  Now my virus guard is showing that i have another 600 days of protection. But 2 days ago i got a email from macafee that my subscription has ended . I dont understand. How could that happen.
