“Tiempo en colombia en vivo” is the name of the invading Chrome extension. Malwarebytes doesn’t provide any specifics about what this extension actually does to Chrome but presumably, it completely hijacks the browser to push technical support scams, drive click numbers on specific websites, or completely hijack web searches. The company’s listing says it could spy on your web browsing activities too.
It’s essentially force-installed by hijacking the browser on websites supporting the extension. If you try to leave the page, a popup appears asking to add an extension for exiting the page. If you select cancel, another popup will appear with an additional tick box that says “Prevent this page from creating additional dialog.” Check the box, hit “OK,” and the browser goes full screen with a popup revealing the name of the extension that is supposedly distributed through the Chrome Web Store.
Meanwhile, the Firefox extension takes a different route. Victims will see a web-based advertisement warning that Firefox requires a manual update. Taking the bait, they inadvertently install the offending extension, which prevents them from accessing the internal “about:addons” page by closing the tab. To remove the extension, you can restart Firefox in safe mode. Extensions are not active in this state, thus you can remove any add-on before restarting the browser.
Believe it or not, Task Manager is your best friend in Windows. Simply type CTRL+ALT+DEL, and you can open the Task Manager window to force-close any browser tab that refuses to close. You don’t need to install anything to escape the clutches of a malicious web page. Even more, Google and Mozilla absolutely do not send warning advertisements on web pages to manually upgrade your browser. Updates are typically performed behind the scenes.
