ScanEventHandler

ScanEventHandler is a browser hijacker that may redirect your browser to unwanted websites or promote third-party advertisements. Errors associated with ScanEventHandler also may occur from conflicts between legitimate drivers and Mac operating system updates. Users should remove ScanEventHandler through appropriate security solutions if symptoms align with browser hijackings, and in benign cases, update all appropriate software or disable the conflicting driver temporarily.

The Crucial Differences Between Browser Add-Ons and Update Glitches

When it comes to the macOS, users would be right in assuming that they're at risk from very similar adware, browser hijackers, and other Potentially Unwanted Programs to others on Windows or Android. ScanEventHandler is an example of a PUP that provides Web-surfing inconveniences for apparent profit but also has another side. This browser hijacker's name also has past associations with relatively-harmless driver bugs.

As a browser hijacker, ScanEventHandler is software that redirects users to unwanted sites. It may hijack settings related to homepages or default search engines and reroute traffic to affiliate sites for generating revenue. Some users also may experience unwanted advertisements, such as pop-ups. Like similar PUPs, ScanEventHandler isn't threatening enough that it merits classification as a Trojan but remains an overall security hazard and a detriment to the browser's performance.

The above isn't all to ScanEventHandler's story. Possibly the cause of the unknown developer's choice of the software's name, ScanEventHandler also has strong associations with driver bugs from non-PUP software. The most typical example is an updated GateKeeper installation flagging a driver as threatening by mistake. The problem may create repeated error messages, such as 'ScanEventHandler.app will damage your computer' prompts. Since the warning message also is commonly-appearing in PUP installations, macOS users who don't spot the difference may either brush off a real security dilemma or take a minor update bug too seriously.

Handling an Event of Ambiguous Software

Users normally will see obvious symptoms of browser misbehavior from browser hijacker installations like ScanEventHandler. These changes may impact multiple browsers, and reversing the settings will not remove the software that's responsible for causing them. Due to the exposure to third-party sites and advertisements posing security concerns, our malware experts recommend users limiting their Web-surfing through browser-hijacked browsers, when possible.

However, if there are no symptoms and security services to confirm no results during system scans, a ScanEventHandler alert could be a false positive. Updating the driver or the macOS may correct this problem and eliminate the Gatekeeper alerts. If not, malware researchers recommend that users remove or disable the driver temporarily until Apple or the appropriate company corrects the identification issue.

For safety's sake, users should have trusted anti-adware or anti-malware solutions scan their computers for threats after any warnings related to ScanEventHandler. Manual removing ScanEventHandler is likely of both missing components and running into more identification errors, and malware experts recommend against it for most circumstances.

Telling the difference between two different problems with similar names isn't easy necessarily, in the software world or anywhere else. That fact is why security products exist, helping users by doing the hard work of flagging ScanEventHandler for them.
