What is Quantum Ad Blocker
Quantum Ad Blocker is supposed to be a browser extension that will blocks ads on visited websites and improve the browsing experience, but according to security professionals, this extension acts as adware. Adware software is considered by many to be synonymous with ‘malware’. It’s a malicious program that displays unwanted ads to computer users. Some examples include pop-up ads, push notifications or unclosable windows. Clicks on the ads produce a monetary payoff for the adware developers. Adware can work like Spyware, since it sends user data such as searches and trends to advertisers. Adware can be installed onto computers via infected websites, when users open email attachments, anytime users download and install free software.
Unwanted ads
Does adware steal your data? Quantum Ad Blocker can gather privacy info about you such as what webpages you are opening, what you are looking for the Web and so on. This privacy information, afterwards, may be sold to third parties. Therefore it’s very important to follow the instructions below without a wait. The few simple steps will allow you to remove Quantum Ad Blocker as well as clean your web-browser from unwanted advertisements. What is more, the instructions below will allow you remove other malicious apps like undesired toolbars and browser hijackers which can be installed onto PC system along with the adware software.
How does Quantum Ad Blocker get on your PC system
The most common way to get adware is a freeware setup file. In most cases, a user have a chance to disable all additional modules, but some setup files are developed to confuse the average users, in order to trick them into installing PUPs and adware. Anyway, easier to prevent adware software rather than clean up your PC after one. So, keep your internet browser updated (turn on automatic updates), use good antivirus applications, double check free software before you start it (do a google search, scan a downloaded file with VirusTotal), avoid malicious and unknown web sites.
