Auto Purge extension for Chrome may expose users to potentially dangerous third-party sites

Auto Purge extension for Chrome is a tricky third-party tool that promises potential users many useful features, while in reality, it can hardly fulfill any of them. Prevent tracking of search history, stop advertisements from chasing you, and cleaning Chrome's history automatically are the three things that this tool promises to do. However, do not fall for believing it blindly because this extension has recently been classified as a browser hijacker and potentially unwanted application (PUA) due to intolerable activities.
Based on the NoVirus.uk[1] researchers, Auto Purge has been spreading in disguise with freeware as a pre-selected component (hidden under Quick installation setup). Consequently, it reached thousands of computers without users' authorization. Its primary goal – to set sponsored Bing search instead of a default search engine, replace start page, new tab window, and other Chrome settings to make people see the content of its sponsors and take control over users' web traffic.
Thus, even though this dubious extension promises its users to disable ads and improve their online privacy, it disables original ads and replaces them with the content of its sponsors, promotes questionable third-party websites, and injects its own cookies to monitor users' web browsing activities. Therefore, it's advisable to remove Auto Purge extension from Chrome without a delay.

The Auto Purge extension for Chrome promises to disable third-party content, including intrusive advertising and cookies that disrupt web browsing activities and interfere the privacy. The problem is that the extension is sponsored by third parties, meaning that it is programmed to show the content of its sponsored for an agreed commission fee. Here's an excerpt from the EULA[2] of the extension:
The Services may contain links to other Internet websites and services owned by third parties. Your use of each of those websites and services is subject to the conditions, if any, that each of those websites has posted. You acknowledge and agree that we have no control over websites that are not ours, and we are not responsible for any changes to and/or content on them. Our inclusion of any third-party Content or a link to a third-party website or service is not an endorsement of such third-party content or third-party site. […] Any questions, complaints, or claims related to any product or service should be directed to the appropriate third party.
The Auto Purge redirects should not be tolerated because no one knows what parties initiate them and what content is positioned behind. In the worst-case scenario, you may get exposed to phishing sites where you may be offered to participate in prize giveaways in exchange for your personal details (first name, last name, telephone number, e-mail address, home address, etc.). In addition to that, you can also be tricked into visiting malware-infected websites that spread malware like Auto Refresh, Dirty Tinder, CookieMiner, and others.

Apart from rather aggressive advertising, Auto Purge removal is recommended to improve privacy security. The extension is represented as a tool that protects privacy. On the one hand, it blocks third-party cookies. On the other hand, it enables its own cookies and web beacons to record personally non-identifiable information (PII) and then shares it with the sponsors for marketing improvements.

- Search Term;
- Ad clicked, Organic/Web results clicked & Search Engine Overridden;
- User-Agent.
Therefore, we strongly recommend you to remove Auto Purge virus from your machine. It does not have a real value, except ambiguous activities. Luckily, it's removal is not too difficult – a manageable task for less experienced PC users. You can select either manual or automatic removal option.

Manual Auto Purge removal should be initiated in stages, i.e. PUP removal, extension removal, and full system optimization. Users can find manual elimination guidance and recommended anti-malware tools at the end of this article. Additionally, we recommend not leaving the system caches with outdated registry entries. This task can be initiated by FortectIntego optimizer.
Make a research on any freeware before installing it
This Chrome extension has the official download website where it is promoted in a rather appealing manner. The download costs nothing and, we believe, that people who accidentally land on this site may decide to tithe this browser-based a try. However, direct downloads are very rare.
Usually, PUPs like this are downloaded in bundled[3], which is why users often don't even realize that they have installed unwanted applications. The so-called “bundling” is a method known for ages, though for the last ten years it has been misused for distributing PUPs and other malware.

That's why it's so important to download freeware purposely and deliberately. Choose official websites if possible, download freeware by picking up the Advanced/Custom installation technique, reject the installation of additional components (add-ons, toolbars, plug-ins, etc.).
Ways of getting rid of Auto Purge malware
Remember that Auto Purge virus is capable of displaying third-party content, initiated ongoing web browser's redirects, and collecting browsing-related information behind your back. Even though it cannot be called a virus, the content it returns can be misleading or even dangerous.

Therefore, we recommend people to initiate a full Auto Purge removal as soon as it starts showing signs of presence. The easiest way to do that is to run a full scan with a robust anti-malware tool. Nevertheless, the web browser's settings will have to be restored manually.
When you remove Auto Purge-related malware from the system, you should open the web browser and delete the extension manually. First of all, disable the extension and then delete the search engine. At best, restore the default Chrome's settings.
