Noooo!!!
I can't stand McAfee and I'm a longtime paying TunnelBear user.
I just know that McAfee is going to pollute the TunnelBear app with their "security" bloatware.
Ugh.
I installed McAfee software once-- that experience put McAfee on my 'never again' list. I don't use TunnelBear, but know many who do. I sincerely hope they leave it alone.
I use windscribe and get a generous allowance free. Is tunnelbear considered a better vpn?
I have paid TunnelBear, paid PureVPN (Black Friday deal) and free Windscribe. I think they're all pretty good.
If free Windscribe is meeting your needs then I see no reason to change.
