AVG and OPERA Browser

Whenever I open Opera now I get an "API.USERAGENTSWITCH.COM" infect with URL:Blacklist. There has been no change to the system. No issues on any Virus/Script scan. What has changed?

Hello Joe, 

Thank you for sharing the screenshots. Could you please reset the opera browser once and check whether you can access it without any issues? If you still get the error, kindly share the screenshot by clicking see details option in the detection. Please refer the below article to know how to reset the browser :

Reset the browser corrected it. Thanks. Now just have to add back my extensions and should be good to go.

The real issue I found is the "User Agent Switching" extension which I have used for years triggers AVG. The extension allows me to change the type of "browser" type I am using to test web pages. So i can tell Opera to appear as an "iPhone" or Android device, or a Firefox Browser or an Edge browser all without leaving the browser. This extension has been safe for years. I guess I'll have to turn off the WebShield whenever I need to testing. It possibly may appears as a browser Hijack unless you whitelist it.
