Charter has another company design their security suite. Over the past few years they have used F-Secure and McAfee, I know for sure though F-Secure has done it in the past, and to be honest their security isn't all that bad. I don't use antivirus software but F-Secure labs in located in Finland and they are one of the few AV vendors that include things like governmental malware in their scans. But F-Secure isn't bad when you get it directly from them, but the charter Security suite is super bloated with pups atm which charter gets paid by advertising networks so they can sell your searches etc online. That is how they are able to give it to you for free is by selling your interests etc online to these advertisers. So charter Security is good in the sense that it uses the F-Secure engine and database, but lacks in a lot of other privacy areas. If I was you I would get Malwarebytes premium because right now I think some stores are selling life time licenses for their software.
