WeatherGrind is a useless desktop application that claims to provide you with local weather information from your desktop; however, we have found that this is yet another potentially harmful adware application that comes from the same creators who developed DraftFactor, Movie Megs, and PocketRebates as well. Practically, this program does not have anything beneficial or useful to offer for you; nothing that you could not do much better, safer, and more reliable by surfing the web in your preferred browser. Therefore, we consider this software totally redundant and useless, not to mention the fact that it may show you potentially unsafe third-party web content. Engaging with such content could pose a threat to your system security. That is why we think that you should remove WeatherGrind; and the sooner, the better. Keeping this application on board may increase your vulnerability. However, this adware may not even be the only threat you should tackle. Find out more by reading our full article.

Although there is a promotional page, weathergrind.com, where you could download this annoying application, you should know something about this page, if you have not landed on it yet. When your computer is protected with an up-to-date security tool, you cannot even load this page because it gets red flagged right away as it is detected potentially harmful. We have realized that it could be due to the fact that the official installer of this adware is actually a bundle that packs a number of potentially unwanted programs, browser hijackers, and adware programs, including Search Know, Sweet-page.com, and MyPcBackUp. It seems that these infections can vary from region to region and also, time could be another factor. However, it is quite clear that if you have installed this version, there can be a number of malware threats on your computer. This obviously means multiple risks to your virtual security; so if you do not act in time, your PC and your Internet speed may become slower, and you may infect your machine with even more malware programs. Because of the heightened possibility of exposure to cyber criminals, we advise you to delete WeatherGrind and all other related suspicious applications as well.

But this is not even the most likely way for this adware to show up on your PC. As a matter of fact, we have discovered that this infection can mostly come through unreliable third-party ads, such as download offer pop-ups. These can be displayed either by suspicious file-sharing websites if you are visiting one or by adware applications that are hiding on your computer. There is also a chance that it might come in a bundle; therefore, you could infect your system with several malware programs in one go. As you can see now, if you find this adware on board, you should not stop at deleting WeatherGrind alone.

When you start up this program, it opens its window that is quite characteristic for all applications in this family. At the top-left corner, you can see a large logo and below that, a promoted website loads. In this case, since this adware is all about local weather, you may find wunderground.com in the window. However, this site seems to be the only one you can check through this program. So you cannot even use it for viewing anything else. It is like having a browser that only shows you one single website. What sense does it make? This application may also open an additional Internet Explorer window and load promoted websites into it, but it may also expose you to third-party advertisements. Clicking on any content this adware offers would be quite risky; therefore, we do not advise it. In fact, we recommend that you remove WeatherGrind as soon as possible because one wrong click may take you to malicious websites where you may get scammed by criminals. So let us share with you what you can do to eliminate this threat.

As a matter of fact, we can offer you a couple of solutions if you are ready to step up and delete WeatherGrind and all other potential threats. First, you can simply uninstall this annoying adware through Control Panel. The second option is mainly meant for more experienced computer users since it involves editing the Windows registry. Please use the manual guide at your own risk, i.e., if you know what you are doing. Please find instructions for both options below this article if you need help. However, there is yet another option that is indeed the most efficient and most comfortable as well. You can also use a professional anti-malware application that will automatically tackle all security-related issues in your virtual world.
