The UpgradeAssist application appears to target Mac users exclusively. This utility may present itself as a useful tool that will assist users in installing software on their Mac computers. However, this is not the case. The UpgradeAssist application is identified as adware, and you should not install this fake utility on your computer.
The UpgradeAssist adware will begin injecting advertisements in the sites you are visiting, as soon as you install it. This means that you will begin seeing far more advertisements whenever you browse your favorite pages. The UpgradeAssist adware may expose users to advertisements for unsafe products and fake services, so it is best to avoid interacting with any of the advertisements affiliated with the fake application.
If you have not installed the UpgradeAssist utility on your computer purposefully, it is likely that it found its way into your system via a free software bundle. Users who rush through the installation process of free software may end up overlooking important details and may consent to install PUPs (Potentially Unwanted Programs) or adware on their computers. If the UpgradeAssist tool is present on your Mac, it is best to remove it with the help of a reputable anti-virus product immediately.
