Search Results LLC or Default Tab is an adware program that hijacks your search engine to redirect you to results that include extra advertisements. Because Search Results LLC has a history, like many other adware applications, for resisting being removed by the usual means, you shouldn't hesitate to use a trustworthy anti-malware application to delete Search Results LLC and return your browser back to normal.
 
While there aren't signs of Search Results LLC's results including drive-by-downloads, phishing attacks or other types of harmful content, Search Results LLC may include an excessive amount of advertisements – and doesn't provide uniquely-relevant results, in any case.
 
After a few searches with Search Results LLC, it shouldn't take long to most people realize the above facts, but Search Results LLC appears to have implemented safeguards against its PC users avoiding its search services. Search Results LLC's add-on may replace your default search engine and not allow you to change your settings to reverse the modification. Search Results LLC is unusually stubborn during uninstallation and may refuse to be removed via the Windows Control Panel or any other methods that would delete normal applications from your computer.
 

How to Get Your Results the Way You Want Them

 
Since Search Results LLC changes your browser's settings in negative ways but doesn't make any attempts to expose you to dangerous web content, Search Results LLC only can be considered a low-level threat to your PC's safety. To keep your chances of being redirected to undesirable websites, SpywareRemove.com malware researchers advise you to keep your browser updated, use strong security settings and avoid downloads from sites that you don't trust.
 
Putting an end to Search Results LLC's redirects requires the complete removal of Search Results LLC's adware add-on. However, while normal program removal techniques aren't adequate for doing this, most types of anti-malware scanners should be capable of finding and deleting Search Results LLC in short order. As long as you do this as quickly as possible, there are negligible chances of your PC being harmed in any other way from a brief Search Results LLC infection.

    Good Morning. I am a small business I.T. consultant and of course most small businesses have 5-10 people and often have someone in the office encountering these issues. Your focus on this page was Search Results LLC but does your product respond well to most malware/adware? Do you have a version that I can use and remove to reuse as needed without violating any licensing agreements. I've got a system on my desk right now that I need to back to the user and have gone to great length to remove this particular problem, DefaultTab, with no success. Many Thanks, --Tony
