DownChecker is supposed to help you manage your software updates, and users often install it because it is offered free of charge. Even though this program is not available from downchecker.com, it is promoted via other sites, most of which are not that reliable. Our hopes are that users do not trust unreliable installers and stay away from malicious sites, but practice shows that users are careless. If you are careless as well, it is not surprising that you now need to remove DownChecker. Fortunately, we know an easy way to delete this program from your Windows operating system.

Even though you must have downloaded DownChecker from a third-party source, you might be familiar with downchecker.com. This website offers a great deal of information related to this program and its activity. For example, most users need only to glance at the EULA to realize that DownChecker requires removal. This document reveals that DownChecker “is sponsored by third party advertisements and commercial offers and may also contain links to third parties websites, advertisements, products, offers, applications and more.” If we know one thing about unfamiliar advertisers is that they can be very unreliable, which is why most ad-supported programs deserve removal. Despite the fact that DownChecker can show ads, we identify it as a potentially unwanted program (PUP) rather than an ad-supported program.

Most users who download DownChecker do not take enough time to research this PUP. For example, if they checked the EULA, we are sure that they would think twice before installing it onto their operating systems. Unfortunately, users are often careless, and they install unreliable programs without understanding fully how they work. In fact, many users are confused about the ads that start showing up after installing this PUP. After all, DownChecker is meant to work as an update manager, not an advertising tool. In cases like this one, we always recommend installing a legitimate and trustworthy malware scanner to figure out what’s going on. If you are quick to react, you might catch and remove malware before any damage is done.

While we do not call DownChecker a malicious program, it has some features of an unreliable program. This is why we believe it is best to remove it from your operating system. Can you delete DownChecker manually? We hope that the manual removal guide will help all users to get rid of this potentially unwanted program. Alternatively, you can use automated malware removal software, and this might be a better option for many different reasons. For example, it can solve all of your problems regarding other computer infections. As mentioned previously, DownChecker can be distributed by other parties, and it is possible that they will bundle the PUP with malicious infections. Needless to say, you MUST remove them as soon as possible.
