I do not use the Xfinity Gateway and have received the same email as everyone else - the link works for the free trial and reduced rates for Norton:
Norton 6-month trial exclusively for Xfinity customers
You can also choose to continue your protection through Norton. Norton has two exclusive offers for Xfinity customers using Norton Online Security. These two plans give you comprehensive device security, including antivirus, password manager, and more. Plus, you’ll get a 6-month free trial.
When you sign up, your free trial will begin right away.
The blue signup above is a clickble link.
That said, you need to do some research, decide what protection you need and what your budget can afford. You can also read thru the threads here on this forum and see what others have suggested.
Bottom line is you have to decide which is best meests the need for protection for your system(s).
Most Customers know by now that Comcast will not be providing free AntiVirus software from Norton as of 01/01/2021. Temperary Alternatives are Available.
Please Reply with more suggetions.
I state these are temperary alternatives, because nothing beats or gives you peace of mind, like a good fully functioning paid for antivirus software.
P.S. One could go for almost a year skirting on free offers from all the antivirus software companies out there! 😀
