My Weather Radar

My Weather Radar is an extension for Mozilla Firefox and Google Chrome users and an application for Internet Explorer users created by Polarity Technologies Ltd. The extension/app is advertised as a tool that can provide users with the latest weather information, which is why it does not appear to be useless or malicious at first. Unfortunately, installing it could be dangerous, and our malware research team strongly recommends deleting it from the browsers and operating system if it was installed. It is most important to get rid of this potentially unwanted program (PUP) because it acts as a browser hijacker. Once you install it, the suspicious takes over. On Chrome, it only takes over the New Tab, but on Firefox and Internet Explorer, it can also hijack the homepage and the default search provider. According to our research, it is not always enough to remove My Weather Radar to have the hijacker eliminated too. Continue reading if you want to learn how to eliminate the PUP and the hijacker, as well as if you need more information on why doing that is important.

The suspicious My Weather Radar is introduced to Mozilla Firefox and Internet Explorer users via the official download page,, but Google Chrome users can acquire it from the Chrome web store at It was found that these sources are not the only ones that are used by Polarity Technologies Ltd. to spread the PUP. This company stands behind,,, and many other browser hijackers that are associated with unique potentially unwanted programs, all of which, of course, should be deleted. The company is known to employ third-party installers for distribution. Also, it appears that misleading pop-up offers could be used to promote My Weather Radar as well. If you end up acquiring the PUP from a strange source, it is important to check if other threats that require removal exist on your operating system, which you can do using a legitimate malware scanner. That being said, you need to be careful about the “official” sources too. When testing the PUP, we found that the Chrome web store installer pushed to install the Search Encrypt extension as well. Be careful about any additional offers.

As you might have realized already, My Weather Radar was built to represent The interface of this page reminds of a search engine with additional links to third-party sites. Some of these links include,, and Since these represent weather-related websites, some users might think that My Weather Radar is a beneficial tool. That is not the case, and, in fact, the seemingly useful links are only meant to make you think that the suspicious can be trusted. It cannot be trusted. All search queries are redirected to Yahoo Search, and even if you think that this search engine can be trusted, you need to understand two things: The redirecting is unauthorized, and the search results can be modified. If the hijacker can redirect you to one page, it could potentially redirect you elsewhere as well. And when it comes to the search results, interacting with them can be dangerous because the creator of the hijacker could inject anything along with real results. This is exactly why it is strongly recommended that you delete this suspicious software.

We offer a manual removal guide that shows how to delete My Weather Radar. As you can see, it is enough to eliminate the unwanted extension on Chrome and Firefox to get rid of the hijacker too. However, if you uninstall the application – which is what you need to do if you operate via Internet Explorer – you will need to change homepage and search provider settings separately. After you remove My Weather Radar, you also need to install a reliable malware scanner to inspect your operating system. If other threats exist, they must be eliminated as soon as possible. What if you cannot get rid of all threats and PUPs active on your operating system yourself? If that is the case, you need to install anti-malware software. This is not the worse option, and, in fact, we strongly encourage all users to acquire this software as soon as possible because only it can simultaneously clean the system and ensure its full-time protection in the future.
