How to remove the OnlineExplorer adware?

What is OnlineExplorer adware?

OnlineExplorer is the name of a potentially unwanted application (PUA) designed to operate as adware and a browser hijacker - it generates advertisements and promotes a fake search engine (its address). It is worth mentioning that applications like OnlineExplorer usually are distributed using deceptive methods.

OnlineExplorer in detail

OnlineExplorer generates advertisements (for example, banners, coupons, pop-up ads, surveys) designed to open questionable websites. Typically, by clicking ads generated by apps like OnlineExplorer, users open websites like "MALWARE DETECTED Action Required", "Receive iPhone 12", "Congratulations! Netflix User!", and similar pages.

Also, OnlineExplorer may generate ads designed to run certain scripts and download or install other potentially unwanted applications. Therefore, it is strongly recommended not to click advertisements generated by adware (including the OnlineExplorer application). Another problem with OnlineExplorer is that is changes web browser's settings.

More precisely, OnlineExplorer changes settings such as the address of a default search engine, homepage, and new tab. This app changes them to an address of a fake search engine. Fake search engines show results generated by legitimate search engines like Google, Yahoo, or they show results that may include links to potentially malicious sites.

Also, fake search engines can be designed to display advertisements. Typically, those advertisements should not be trusted as well. Another detail about browser hijackers is that they do not allow users to undo their changes. It can be done only when browser hijackers are no longer installed.

Additionally, it is likely that OnlineExplorer collects Internet Protocol addresses, entered search queries, visited websites and other information related to browsing activities. Also, this app could be capable of accessing credit card details, passwords and other sensitive information.

Adware in general

OnlineExplorer and similar applications display advertisements and promote fake search engines. Most of them do not have any useful features and can cause various problems. More adware examples are BestForMac, DataBoost, and WebResultsTool. Typically, users download and install adware (or PUAs of other types) unknowingly.

How did OnlineExplorer install on my computer?

It is known that adware-type applications often are distributed via fake installers. It is important to mention that fake installers can also be used to distribute malware (for example, ransomware). To trick users into downloading and using those installers, their developers use deceptive websites.

Another way to distribute PUAs is to include them in downloaders and installers for other programs as optional offers. This distribution method is known as "bundling". Users download and install PUAs when they leave "Custom", "Advanced", "Manual" or other settings unchanged, or when uses do not untick ticked checkboxes.

In some cases, users unintentionally download or install potentially unwanted applications by clicking advertisements designed to execute certain scripts. As a rule, advertisements of this type appear on dubious, deceptive websites (it is unlikely for them to appear on legitimate, trustworthy websites).

How to avoid installation of potentially unwanted applications?

It is recommended to examine downloaders and installers that have settings like "Custom", "Advanced", "Manual", or other settings. Quite often, they are used to distribute potentially unwanted applications. Those settings should be checked before finishing downloads or installations.

Software (and files) should be downloaded from legitimate, official pages and through direct download links. Other sources like third-party downloaders, unofficial pages, Peer-to-Peer networks (for example, torrent clients, eMule) should not be used. Third-party installers should not be used too.

Additionally, it is recommended not to trust advertisements that questionable sites have on them. Those ads can be designed to promote untrustworthy websites or cause unwanted downloads, installations. Unwanted, unknown, or suspicious extensions, add-ons, or plug-ins installed on a browser (or programs of this kind installed on the operating system) should be uninstalled.

If your computer is already infected with OnlineExplorer, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
