How to uninstall ExpandedActivity adware from the operating system?

What is ExpandedActivity adware?

ExpandedActivity is designed to display unwanted advertisements and promote a fake search engine by modifying browser's settings. In other words, ExpandedActivity is designed to function as an adware-type application and a browser hijacker. Like most apps of this type, it is distributed using deceptive methods.

ExpandedActivity adware in detail

Adware-type applications like ExpandedActivity generate annoying advertisements designed to open questionable websites. In some cases, those ads cause unwanted downloads or even installations by running certain scripts. For these reasons, it is strongly recommended not to trust advertisements generated by ExpandedActivity and similar applications.

A couple of examples of ads that ExpandedActivity is likely to be designed to generate are banners, surveys, coupons, pop-up ads. If clicked, those ads may open websites like "MALWARE DETECTED Action Required", "Receive iPhone 12", "Apple Platform Security", or other pages designed to extract sensitive information or to trick visitors into installing unwanted software.

Furthermore, ExpandedActivity is designed to hijack a browser by changing its settings such as the address of a default search engine, homepage, and new tab. It changes those addresses to an address of a fake search engine. Therefore, its users are forced to visit a specific address each time they open a browser, new tab, or enter search queries into the URL bar.

It is worth mentioning that fake search engines can be designed to generate misleading results (to promote shady websites). In other cases, they could show results generated by a legitimate or untrustworthy search engines. Typically, users cannot remove a fake search engine from browser's settings unless they uninstall a browser hijacker.

One more important detail about ExpandedActivity is it may be designed to collect information that could be misused for marketing purposes, sold to third parties (potentially cybercriminals), used to make unauthorized transactions, purchases, steal identities, or misused in other ways.

Less harmful adware-type apps collect IP addresses, visited websites, entered search queries, geolocations, and other details of this kind. Nevertheless, other adware-type apps can also read credit card details, passwords, telephone numbers, and other sensitive information.

ExpandedActivity adware in general

In conclusion, ExpandedActivity is an untrustworthy application designed to generate advertisements and alter browser's settings. It is not safe to have this app installed on a browser and (or) the operating system. It users should remove it as soon as possible. More adware examples are MainCharacterSearch, AphroditeLookup, and ProductiveUnit.

How did ExpandedActivity install on my computer?

Adware can be distributed through fake installers (many adware-type apps are distributed through fake Adobe Flash Player installers). It is important to know those deceptive installers can be designed to install ransomware, Trojans, or other malicious software. Typically, fake installers are promoted via untrustworthy websites.

Another way to distribute PUAs is to include them in downloaders and installers as optional offers. When users download or install programs that are bundled with PUAs without changing "Custom", "Manual", "Advanced", or other options, they agree to download or install those apps as well.

Also, potentially unwanted applications can be distributed through deceptive advertisements by designing them to execute specific scripts. Those advertisements appear on questionable, untrustworthy websites. Users unknowingly download or install PUAs by clicking them.

How to avoid installation of potentially unwanted applications?

It is recommended not to use Peer-to-Peer networks (like eMule, torrent clients), unofficial websites, third-party downloaders, and so on as sources for downloading files, programs. Third-party installers should not be used too. Files and programs should be downloaded only from official pages and via direct links.

Downloaders and installers for other programs with settings like "Advanced", "Custom", "Manual" should be checked for offers to download or install potentially unwanted apps. Those offers should be declined before completing downloads and installations. Intrusive ads that appear on shady pages should not be trusted (clicked).

By clicking ads on dubious pages, users often open other shady pages or cause unwanted downloads and installations. If there are any suspicious, unwanted extensions, plug-ins, or add-ons installed on a web browser, they should be removed. The same should be done with software of this kind that is installed on the operating system. If your computer is already infected with ExpandedActivity, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
