Power Blocker is a potentially unwanted add-on for Firefox, Chrome, and other popular browsers that constantly injects obstructive ads in the browser. Power Blocker also gathers telemetry data from the browser and later uses it to generate more relevant ads in order to gain more clicks on them.
The excessive exposure to different aggressive commercials (such as pop-ups, page-redirects, banners, ads, new tabs, redirect links, etc.) can be very annoying and has the potential to ruin your overall web surfing experience, especially when it is caused by an adware program like Power Blocker or Wave Browser. This type of software is far less dangerous than real computer threats such as viruses, Trojans and Ransomware but it could still be quite unpleasant having it on your computer. Unfortunately, adware can be encountered all over the Internet, mostly in the form of a bonus or additional component added to some other free programs or software bundles. Many users end up with it when they perform a careless installation of some games, add-ons, updates or free tools. In case that your web browsing has recently been getting disturbed by “ads generated by Power Blocker” and your Chrome, Firefox or Explorer browser has started to spam your screen with hard-to-remove sponsored messages, then we suggest you remain on this page and read on the information that follows. In the next lines, you will find a special removal guide which contains a set of instructions and screenshots that will explain to you how to uninstall Power Blocker and remove its nagging ads from any browser. If you follow the instructions carefully, you should have no trouble eliminating the adware from your system, especially if you combine them with the professional assistance of the suggested removal tool. After you finish with the steps, however, remember to read through the rest of the article to gain a better understanding of the typical traits of the adware applications and their nature as well as the potential issues that they may cause if you let them operate for too long.
Is it really bad if you have adware on your system?
Questioning the nature and the purpose of every new and questionably-looking application that you detect on your computer is a must if you want to prevent nasty viruses and malicious pieces of software (such as Rootkits, Spyware, Ransomware, etc.) from entering your system. That’s why it is perfectly normal to be concerned about the presence of adware apps like Power Blocker even if they lack the harmful features of an actual computer threat. In fact, in many cases, the people who face such software may initially mistake it for some virus due to its aggressive ads generation and automatic page-redirects that it may initiate. But this is mostly due to a lack of understanding about the real nature of the adware rather than some actual maliciousness. The main reason Power Blocker tries to fill your monitor with ads is that it wants you to click on them and to visit some pre-defined domains which have paid for getting promoted by the adware. Similarly to other ad-generating and page-redirecting applications, the adware generates profits for its developers through the clicks on its ads on a pay-per-click basis. There is nothing illegal in this advertising approach but if you find that your regular browsing has been getting disturbed by it, you can use the removal guide on this page to permanently uninstall its source.
|Danger Level||Medium (nowhere near threats like Ransomware, but still a security risk)|
|Symptoms||Different ads, pop-ups and banners may start spamming your screen during your regular web surfing.|
|Distribution Method||Software bundling, automatic installers, torrents, spam, ads, freeware, shareware.|
Some threats reinstall themselves if you don't delete their core files. We recommend downloading SpyHunter to remove harmful programs for you. This may save you hours and ensure you don't harm your system by deleting the wrong files.
