Remove MultiSet
The MultiSet app for Macs is not reliable. It might be installed without your permission and approval. This usually happens to users who frequently download installers from non-trustworthy sources. MultiSet is a Potentially Unwanted Program (PUP) that could reach your system through fake downloads, software bundles, and other misleading content. Thankfully, it does not possess any harmful qualities, so its presence on your system is not a critical issue. However, we should warn you that MultiSet could become the reason for unexpected changes to your Web browser's behavior and settings.
The changes that MultiSet brings usually concern your browser's default search engine and new tab page. The application will redirect you to 3rd-party search engines that rarely deliver reliable results. In fact, using them is likely to expose you to unwanted ads, sponsored results, and other intrusive content.
Trying to restore your browser configuration might be impossible, because MultiSet will undo these changes immediately. This is why your top priority should be to remove MultiSet from your Mac. The proper way to handle the task is to run an up-to-date security scanner. This is the only way to ensure that all of the PUP's files are gone, and that none of its components will continue to pester you.
After removing the MultiSet PUP, you should consider using reliable antivirus software to protect your Mac system in the long run. This is the best way to avoid future encounters with malware or intrusive Mac apps.
