Once upon a time, Norton LifeLock and Comcast had a fruitful partnership. But their lucrative collaboration was abruptly terminated at the beginning of 2021, leaving Xfinity users with a lot of questions and just as much skepticism regarding their protection.

As it’s often the case, when one door shuts, another one opens. So what is this mysterious new virus protection for Comcast customers?


What is Xfinity replacing Norton with?

With Norton antivirus for Xfinity customers out of the way, Comcast promotes its proprietary digital security solution. The xFi Advanced Security suite is available to users who lease an Xfinity Gateway and (optionally) a Comcast router.

We say it’s optional since there are plenty of routers that work well will Comcast and you can just as easily go for an alternative.

With easy connection via the Xfinity app or directly via the xFi website, this cybersecurity tool operates at the gateway level, thus extending its protection to your entire network and all the devices connected to it.

As promising as it may seem, Internet security for Comcast customers has its drawbacks. From minor hiccups to insurmountable befalls, there is no shortage of examples.

But there is no need to stray so far to justify the necessity of a full-scale antivirus for Xfinity customers. Sometimes, the most obvious reason is also the most important one.

Xfinity xFi Advanced Security is not really an antivirus program.

Do I need an antivirus if I have Xfinity Internet? For those of you who were in doubt, this basic explanation should suffice as clarification.

Now, we are not discrediting Xfinity’s cyber defense solution. If anything, it’s a useful tool capable of securing your home network without hindering speed or performance since it’s deployed at the gateway level and not directly on your PC.

Nevertheless, it is more of a network firewall and not an antivirus for Comcast customers. Consequently, it cannot possibly protect your device against the polymorphic and increasingly sophisticated pool of nastiness that the World Wide Web throws in your direction.

Here are the criteria on which we focused in order to pick the best antivirus for Xfinity customers:

➡ Modular architecture that allows for seamless collaboration with Xfinity’s proprietary security solution
➡ End-to-end versatility (cross-platform compatibility to cover devices running on different OSs and support for simultaneous connections)
➡ Impeccable virus detection rates (100% accuracy is desirable, but anything close to it should be good enough as long as false positives rates are kept in check)
➡ Focus on device performance (small system footprint, less resource-intensive scans, and smooth updates + optimization booster tools)
➡ Plenty of customization options for scans, notifications, and setup
➡ Remediation and reconciliation features to harmonize different software running in parallel, optimize security settings and endorse a fruitful, cooperation-based relationship at the system level
➡ Bonus features (privacy-focused tools, anti-hacking modules, and so on that balance the price/value ratio)

Does Xfinity have free antivirus?

We are not really into long and fancy speeches that say nothing at all in the end. So, to put this quarrel to rest once and for all, here’s a plain answer. Does Xfinity have built-in antivirus? It does not.
