Online advertisements are everywhere nowadays. You see them while you browse the web, surf on social media or read your email. Most of the popping messages you see are generated directly on the web pages you visit. However, there is another online advertising method that forces all sorts of ads, banners, pop-ups and notifications directly on your screen with the help of an ad-generating component that gets installed on your PC. Such software is known as adware and since you are reading this, you are probably facing one adware variant called Important.exe “Virus”. It doesn’t really make a difference what browser you are using – Chrome, Firefox, IE, Opera – they may all be controlled by the adware once it starts operating on your system. The particular program you have on your PC is known as quite aggressive and may constantly feed your browser with unstoppable and irritating ads. Important.exe “Virus” may even apply some undesired changes to your search engine settings and redirect your searches to promotional pages and new tabs, this way causing you a real disturbance and preventing you from browsing the web normally. The good news is that there is a way to permanently stop this annoying activity and clean your system from the ads. What we have here is a removal guide, which will help you manually remove Important.exe and all its traces from your computer. Uninstalling the adware is actually the only way to get rid of it completely, so if you really don’t want to see its nagging ads and pop-ups again, then the information below is just for you.

Can Important.exe be a virus?

When speaking about adware, there is a widely spread misconception about its danger levels that we need to clarify. Many users who are facing the Important.exe’s aggressive ad-generating activity for the first time believe that this is a virus infection almost as dangerous as Trojans or Ransomware. However, this is a wrong statement. Adware, and Important.exe in particular, is not malicious, nor does it have something in common with harmful viruses like Trojans, Ransomware, Spyware or other malware. Indeed, it could be a source of browsing-related irritation to some users, but this is far from what is considered malicious, according to most security experts. Moreover, adware falls in the category of legal software, which is widely used by many businesses, vendors and software developers as a tool that promotes other products or software and converts clicks from the displayed ads into income. That’s why you really have no reason to panic if you have Important.exe on your system. If you wish to remove its ads from your screen, however, you may need to uninstall it with the help of the removal guide below.

A few questionable activities related to adware…

Although adware is relatively safe and does not relate in any way to malware or viruses, there are still some rather questionable activities that may raise your concerns and may add up to your decision to uninstall it. Let’s not exclude the possibility that you may land on some illegal web pages or compromised sites as a result of the intrusive page redirects and new tabs that take over your browser. You never know what may be lurking there, so one of the safety tips is to avoid unknown web locations and push notifications as much as possible. Sometimes the ads, pop-ups and banners may become so aggressive, that closing them may be impossible. As a result, your screen may freeze and your system may become sluggish, which may cause some significant disturbance to your normal web usage. Another annoying thing you may notice is the mysterious way Important.exe matches its ads with your last searches. This is a result of its data tracking activity that monitors your browsing history and the latest pages you’ve visited. Such data is collected with the idea of helping the adware display more relevant ads, but it is not really clear what may happen with this data later and who may access it. With all this said, you now probably have a better idea of why it is advisable to remove this potentially unwanted software from your system.

How to prevent adware from getting inside your system

Adware gets installed on your PC just like any other software does. It needs you to run a setup and agree on installing it by clicking the “OK” button. The specific thing here is that you are very unlikely to download adware willingly on your PC, that’s why it often comes bundled inside the installers of other attractive software, which is usually distributed for free. It could be found in torrents, spam emails, installation managers, direct downloads, file sharing sites, freeware platforms and many more web locations. To prevent its installation, however, you will need to click the advanced/custom option in the setup, which will give you the possibility to deselect it from the installation package. If you skip that option, it will get installed by default along with the software you are installing and you may not see it. This is the most probable way you have ended up with Important.exe on your PC and now to remove it we suggest you closely follow the instructions below to ensure no leftovers remain on your system.
