Rich wants to know if Webroot is a good antivirus utility. Leo says that Webroot is good, and they're a sponsor. They offer additional protections because they're cloud based. But he really doesn't need it. Windows has its own antivirus called Defender that's quite good. Also, the state of malware is such that most occur as 'zero day exploits' which an antivirus can't catch. But Webroot will protect him for the most part. He should remember that his number one defense is his online behavior.
