Ratings and reviews

Love Trend Micro, but when it comes to JavaScript, it's extremely difficult for the uninitiated (like me). I Don't want to know all nuts & bolts about JS, but apparently Trend Micro require JS to activate a product on a Mobile Phone ..

I am giving one star because the ads interfering is so annoying but the app is great but developer make some amend with the ads popping up every single seconds won't make anyone learn

Has content, but "Contains ads" too many non skippable ads frequently, breaks your flow while reading, app would have been much better, but turns out something created only for earning ad revenue.

What’s new

• Added language change option in the side navigation drawer.
• Easily switch and view pages in 50+ languages.
• Works completely offline once downloaded.
• Bug fixes and smoother page loading.
