Not to scare you away from Webroot, but something to think about:
Among third-party antivirus solutions, Webroot is considered much less thorough than other solutions.
Because of this, Webroot has less of a system performance impact on your computer.
For this reason, several years ago, we decided to deploy Webroot Secure Anywhere to over 250 business clients. We installed it on tens of thousands of machines, at least. Had no problems for years.
Then, one day, I want to say in 2016 or 2017, an Oracle SQL database update got flagged in error as malware by Webroot. All of a sudden, our customers could no longer access their databases.
To their credit, Webroot issued a fix within 24 hours, and we had it largely cleared up within a week. But, we spent the better part of a month explaining to angry clients how our choice of antimalware solution caused them to lose access to their key data and business functions for a while.
It was definitely not my favorite month, and one that I won't soon forget.
At the time that we made the decision, Windows Defender was not as well-developed as it is today.
