Online Security Pro Extension

Online Security Pro protects you against malware, phishing and malicious websites.
Protect yourself, your family and your identity credentials against online threats, like phishing and malicious websites, with real-time protection from Comodo.

Online Security Pro extension helps protect you against online threats, such as links in phishing emails and websites designed to trick you into downloading and installing malicious software that can harm your computer.

While you are surfing on the internet, malicious links and phishing URLs are everywhere. So this extension helps you block those phishing urls and malicious links easily.

How are we doing this?

Step 1: When you click a malicious link in an email or navigate to a site designed to trick you into disclosing financial, personal or other sensitive information, or a website that hosts malware, Online Security Pro checks it against a frequently updated list of malicious URLs known to Comodo.

Step 2: If the malicious link matches one on the list, Online Security Pro shows an information screen letting you know that the web page you are about to visit is known to be harmful, and showing options for you to go back to safety, allow and go or report.

Done!

Also, this process does not affect your browsing speed, and you can surf the internet as fast as you can and securely.

Sean McDougall (ID: 000000646cc25f49) Voted 4 ★ - Updated 06/14/2022 Works well and seems to be identical to the Microsoft Defender browser extension that is only available in the USA at the time of writing. When I say identical, I mean that the text used to explain both in the Chrome web store is literally identical, so maybe MS have bought it from Comodo. That at least ought to give some confidence. Would be five stars if I could figure out whether it is functionally any different to using Cloudflare's free anti-malware DNS servers or a decent anti virus program.
