Question

How do I configure TrendMicro to work with K9 Web Protection?

Answer

There is a known bug in the TrendMicro driver which causes an incompatibility with K9 Web Protection. Until TrendMicro issues a fix, you will need to uninstall TrendMicro. You could try installing either Avast! or AVG security programs, as they are known to work well with K9 once configured properly.
