This addition to the Security Suite is good to have looking out for me pro-actively within the browser.

[Addition 2023 Feb 9]
I really would like to be able to right-click on a link and have "Open in Pay Guard" as one of the menu items instead of having to open it and wait for the Pay Guard window to open up. Can't we make this happen.?

Yes, this is not a stand-alone add-on but to add to the system protection from Trend Micro.
I pay for my security since I don't think the safety of your online devices is where to cut corners or costs. There are plenty of other places to economize but, your security shouldn't fall into that category, it's too important.

This is not free. After installing the extension, it doesn't seem to work without the paid desktop application from Trend Micro. They should say it clearly in the description.

Trend Micro has a free add-on for other browsers called "Trend Micro Check Now". I don't understand why they do not provide the same to Firefox users.

信頼していいと思います。

油断はできませんが、これを入れておけば、ひとまず安心かなと思っています。
