ActivityInput is a type of potentially unwanted application (PUA) that can get inside the computer uninvited. This suspicious software also exhibits annoying advertisements on the browser that completely overlay the page content. Because ActivityInput is involved in the excessive display of ads, Mac security professionals have also dubbed it adware or ad-supported software. Apart from the unusual pop-up ads, this adware also causes persistent browser redirects that drive the pages to unsolicited websites.
Infiltration by ActivityInput App
The sudden presence of ActivityInput on Mac computers is mostly due to malicious freeware or shareware downloaded from unreliable websites. Mac users are still not well aware that certain free apps are being utilized by cybercrooks to deploy their programs. Therefore, aside from ActivityInput, similar unwanted applications like LeadingLibrary and GuideRecord were found as embedded objects in freeware, particularly those that are hosted on distrusted servers. As such, Mac users should acquire freeware only from highly reputable and trusted providers.
There are also cases where people behind the ActivityInput app are employing malicious ad campaigns to distribute the adware. In some ads, they claim that the app is a valuable enhancement tool for internet browser applications. According to them, installing the ActivityInput app on the browser will boost Mac users online browsing and searching experiences. On the other side of this malicious ad campaign, ActivityInput may be embedded in a fake software update that is being offered by a pop-up ad purporting to be a system alert. It disguises itself as a system warning that supposedly found system issues due to an obsolete application. The solution would be to download the recommended software update that will eventually load the ActivityInput adware.
Risks of Installing ActivityInput
When ActivityInput is loaded on the internet browser program, Mac users can definitely witness unusual behavior while surfing the web. An unusual number of pop-up advertisements and redirects will show up on the browser window, and this will be a distraction to online users. Furthermore, due to too many ad requests, this activity by the adware could slow down the internet connection. The affected browser program may also post a warning that “ActivityInput will damage your computer.”
The risks of exposing the computer to online threats are likewise possible because of the malicious ads and links from ActivityInput. Thus, it is recommended to act on the immediate removal of this adware to thwart any further risks and restore the browser program to its clean state.
“ActivityInput.gqa will damage your computer” pop-up

To look for potential risks, think about scanning ActivityInput.gqa with an antivirus or antimalware program. Consider removing the file if it is not necessary or if you are unsure about its authenticity. In case you think the alert is erroneous and the file originates from a reliable source, you may opt to carefully disable Gatekeeper by right-clicking and choosing “Open.”
