New Chrome and Firefox malicious extensions prevent user removal to hijack browsers

These extensions are found in both Chrome and Firefox browsers and prevent users from deleting these extensions by either closing the page that extension/add-on information or sending the user to another page, such as an application overview page.

This problem is relatively easy to evade in Firefox, but it requires a lot of work for Chrome, so the quickest way we can suggest to solve it is to report it to Chrome or your favorite security solution so that they can be replaced User handles these malicious extensions.

How to avoid
While the extensions have been around for a few weeks, both are still in use in one form or another. In fact, the Tiempo en colombia en vivo extension was still available in the Chrome Web Store at the time of writing. Unfortunately, since both the Chrome and Firefox extensions mostly add themselves through forced installs, it’s not always possible to avoid getting them. The best we can offer is to stay vigilant as you surf and use an adblocker (that could help with blocking the Firefox extension). Though we’d like add the obvious: Avoid actually downloading these extensions in web stores as well. In fact, it’s a good idea to read the fine print carefully for any browser extension you download.
