ActivityInput – More Information
ActivityInput is the type of program that may be spread on your Mac by being added optionally to installers of other apps. This behavior is known as bundling and we see it used by other apps, like ActivityInput, such as OperativeUnit, RotatorBox and HistoryCollector.
The main way these apps get installed is if they are added in the “Custom” or “Advanced” install modes of another free app you could have recently downloaded outside of official Apple store. Such apps can be YouTube downloaders, converters and other software of this kind. In their installers, ActivityInput could be seen in one of the steps offered as a “free extra” of some sort and this step is usually skipped or well hidden from “Express” install.
Once ActivityInput is in your Mac it may use different trackers to determine information on your online activities. Such information could be tracked by cookies, tags, flash cookies, pixels and other objects dropped on your computer. These objects may be well hidden and may stay years of time if not removed from your Mac. They could be used to collect the following user data from your online browsing:
- The browsing history.
- The sites you have visited..
- Bookmarks you have set up.
- Clicks you have made.
ActivityInput’s main activity revolves around the many ads it shows. These advertisements could eventually lead you to dangerous websites. This is why ActivityInput may not be a virus, but it could be just as dangerous. These ads that you may be redirected to could end up leading you to the following risky sites:
- Scams.
- Tech Support scam pages.
- Fake survey scams.
- Phishing.
- Virus URLs or malware sites.
And you should watch out, because having ActivityInput on your computer could bring the following ads to it:
- Highlighted ads in text.
- Banner promotions.
- Pop-ups.
- Browser redirect ads.
- Ad-supported searches.
- Push notification adverts.
These are the primary reasons to consider removing ActivityInput as soon as you can from your Mac.
