ExtendedField – What Do We Know
Just like other ad-supported programs of this type, such as History Grabber, ExtensionInstallForcelist and PrimaryProcesser, ExtendedField may share similar code, making the possiblity of these apps being made by the same adware developer high.
The main method via which apps, like ExtendedField adware, may land on your Mac is likely via software bundling. This means that you could encounter this app to be included as an optional offer somewhere in the install steps of a typical freeware you may have downloaded. Such freeware apps include media players, file converters, image editors, and others. These apps often contain optionally added software in their installers as a form of making money by advertising such programs.
ExtendedField may begin to change the settings of your web browsers once it has been added to your computer system. Once this is done, the software may then begin to display the following kinds of advertised content:
- Text-embedded advertisements.
- Banner adverts.
- Browser pop-ups.
- Redirects and transfers to third-party sites.
- Ads appearing instead of search results.
- Push notifications promotions.
These ads may contain different trackers that may be used to get the following information from your online browsing activity:
- Pages visited.
- Bookmarked sites.
- Browser history.
- Your clicks made online.
The trackers shown by this software could be of the below-mentioned kinds and they are basically small objects dropped on your mac with years or months of expiration timeframes. This means they could remain and track you for long periods of time, if not deleted.
- Cookies.
- LSOs (Locally Shared Objects, also known as flash cookies).
- Tags.
- Pixels.
- Geo-location trackers.
These trackers are the least of your worries, however. The main problem that has been associated with this software is that the ads it shows are purely there to generate income. The main problem here is that they could sometimes lead to dangerous websites, such as:
- Tech support scams.
- Rogue software download frauds.
- Endless redirect loop schemes.
- Phishing or “Fake” sites.
- Scamming sites.
- Virus domains.
- Scam surveys.
This is the primary reason that makes this software indirect threat to your Mac and makes its removal reccomended.
