internet security

[Stella]

Hi I am running bitdefender 10. My subscription is running out soon. I was
wondering if the windows firewall is sufficient security or if you would
advise additional internet security. thanks

Not an Office question
A Firewall is not sufficient, alone

However you need an anti virus app & spyware/malaware apps (NB both are
required)
You can obtain free versions, Avast, AVG, anti virus apps
MS Defender, Spybot, Adaware, malaware/spyware apps
