Remove ZipArrow
ZipArrow is a Mac program, which you should not allow to run on your device. While it is not dangerous, we consider it to be a Potentially Unwanted Program (PUP.) Typically, software of this type introduces some sort of unwanted changes to your computer. In ZipArrow's case, it appears to manipulate Web browsers in order to promote 3rd-party sites. This manipulation results in random redirects, as well as changes to your browser's default search service and new tab page.
The sites that ZipArrow promotes are usually search engines, but they are not reliable. The low-quality sites that this PUP promotes will deliver extra ads and sponsored results, greatly diminishing the quality of your online searches. Do not be surprised if you find ZipArrow on your Mac even though you do not remember installing it. It might have arrived through a fake download, deceptive ad, software bundle, or even pirated software. To make sure that your Mac is free of PUPs or more dangerous apps, you should secure it with the assistance of a reputable, 3rd-party anti-malware software suite.
