And I get that too. It depends upon what those threats were. That is another "populist" measure - "my AV blocked stuff, therefore it is awesome AV." Stuff can be thrown at AVs that they cannot defend against. All you have to do is look at AV test lab results, which throws run-of-the-mill stuff at them, to see AVs miss stuff. And Webroot does just OK in some areas and poorly against script-based malware. Webroot foolishly whitelists everything Microsoft. Despite all the hype and promises the journaling & rollback algorithms are powerless against a lot of infections, such as screenlock ransomware. It does not protect Windows Firewall and Windows' built-in security settings. It's own journaling registry keys are unprotected. It's not like these areas for improvement haven't been brought to Webroot's attention again-and-again.
Mark my words, someone will say I'm bashing Webroot when in fact I am the one who made the repeated efforts to test this stuff out on Webroot's behalf and jump through Webroot's hoops to report for them.
The bottom line is this... AV, like all security softs, are just an insurance policy, nothing more, nothing less. On the vast majority of systems, it is probability and exposure to low-risk that is protecting the system.
