Bundled Software Uninstaller is a Potentially Unwanted Program often found as a component of Somoto-brand PUPs like BetterInstaller. Ironically, while Bundled Software Uninstaller is distributed as a tool for helping you uninstall Somoto products and other browser-based PUPs, Bundled Software Uninstaller has a history of using improper uninstallation techniques that fail to remove both itself and any associated software completely. Although malware researchers don't consider Bundled Software Uninstaller a major hazard for your PC's security, they do suggest deleting Bundled Software Uninstaller with a good anti-malware program for the sake of optimizing your PC's performance.

When an Uninstaller that Doesn't Work is Half Your Problem

As you'd assume from its name, the Bundled Software Uninstaller rarely is found alone, and usually is part of a multiple-program bundle that uses the Bundled Software Uninstaller as a separate uninstallation utility. Current versions of Bundled Software Uninstaller often lack any publisher or installation information that would be displayed by a reputable program, and Bundled Software Uninstaller also gives no clues as to which programs Bundled Software Uninstaller is meant to uninstall. Since malware researchers have seen Bundled Software Uninstaller accompanied by various PUPs, like the Babylon Toolbar or Better Installer, and also by programs without any visible components whatsoever, the difference in identifiable symptoms between two Bundled Software Uninstaller infections may be significant.

However, most versions of the Bundled Software Uninstaller are tied to the proliferation of adware and browser hijackers, which are known for characteristics such as:

  • Resetting your browser's homepage.
  • Redirecting any online searches to third party sites.
  • The addition of new toolbars for your browser.
  • New advertisements displayed through injected links, pop-up windows, et cetera.

Even though Bundled Software Uninstaller isn't responsible for these functions, its presence usually may coincide with them – and its supposed uninstallation functions will not do anything to remove the associated programs.

Real Uninstall Solutions for Fake Uninstallers

Bundled Software Uninstaller and PUPs related to Bundled Software Uninstaller are not high-level PC threats capable of the same types of problematic attacks as a Trojan or rootkit, but still should be considered overall negatives to your PC's performance and safety.
