To find out the merit of this add-on and the speed to detecting or preventing malicious attacks, I visited some websites known to contain malicious codes. I
In the above screenshot, the attacker uses the Black Hole exploit kit, targeting Windows operating systems and applications installed on those systems. Trend Micro failed to prevent the browser from loading the malicious page and failed to detect the threat. Note that the Internet Explorer SmartScreen Filter is disabled when I visited the malicious webpage, but I decided to visit the webpage once again after enabling IE SmartScreen. Microsoft's browsing protections is fast to detect the zero-day attack as you can see in [inlineImage|link|704c8f195176e8f86f33c3a78d3a500c086ee175||this screenshot].
I decided to visit another webpage that also uses the Black Hole exploit kit to attack Windows and applications installed. Unfortunately, the browser add-on by Trend Micro failed once again to detect or prevent a similar zero-day attack.

Next, I checked the protection by this add-on against another type of exploits --iFrame exploit-- but it also failed to detect the zero-day exploit.
I also downloaded a Trojan downloader program using IE, but Trend Micro's add-on for IE failed to stop the download or the webpage distributing the malicious and unsafe file.
