The Ominent Toolbar is a Potentially Unwanted Program designed by a company known for bundling legitimate browser updates with unnecessary additional software. Currently, the Ominent Toolbar's functions aren't harmful enough to warrants its classification as a true threat, but malware researchers still do consider removing an Ominent Toolbar with robust anti-malware tools to be best for the safety and performance of your computer. Until you do so, the symptoms of an Ominent Toolbar installation usually may include a range of minor but negative browser changes, including homepage hijacks and/or pop-ups.

When a Toolbar Decides Your Browser is Its Own Eminent Domain

The Ominent Toolbar is non-threatening, but undesirable software that exists to promote third parties, including a variety of advertising partners and websites. Because of its highly limited distribution and the general close-mouthed attitude of its Cyprus-based company, malware researchers have been unable to confirm all of the functions implemented by the Ominent Toolbar. However, like other PUPs, the Ominent Toolbar may be expected to use some or all of the following browser features, none of which are helpful to your PC:

  • Homepage hijacks that lock your default start page to an unwanted website.
  • Redirects from search engines and other sites.
  • Pop-up windows that launch unexpectedly.
  • Modified Web pages, including the addition of new text-based links or advertisement banners.

Although these changes don't have any advantages for your browser, neither should they be considered anything more than a minor security problem, in most cases. Despite that, malware experts still would suggest avoiding any obvious signs of hostile content displayed through an Ominent Toolbar's features, such as questionable software updates, system scanners or contests requiring personal information.

Omitting an Ominent Toolbar from Your Browser

WeDownload LTD, the company responsible for the Ominent Toolbar's development and distribution, has remained furtive about their intentions and business model around this toolbar. Even if one is willing to ignore this suspicious behavior, malware researchers have confirmed recent cases of this company maintaining sites that use modified Firefox updates to distribute their products, which explicitly is not allowed by Firefox's Mozilla company. Deleting the Ominent Toolbar, therefore, is a very obviously smart move for keeping your PC as safe as possible, and using anti-malware products to verify that all traces of an Ominent Toolbar have been eliminated is wise.

The prior involvement of software bundles in the history of the Ominent Toolbar's company lends credibility to this being the likely method for the Ominent Toolbar's distribution. If you have any doubt about whether or not a software update is safe, double-check your sources to make sure that you're using a download link that's authorized by the original company. Any other means of acquiring your updates may put your PC at risk for being attacked by threats, not to mention PUPs like the Ominent Toolbar.
