MacOS/Catalina/v10.15.4 -Slow/No Scans; Extensions not compatible
Auto scans haven't been functional for quite some time. Concerning that Trend isn't keeping up with basics... raises concerns about level of protection they provide for their expensive (and poorly suppported) service. Spending lots of time doing manual scans; think I'll spend time looking for new product.
