I got the same thing while downloading PS3 controller driver... I found it in 3 places 1. Internet Explorer> Tools> Manage Add-ons> Search Results LLC: Default Search Tab> Disable 2. Task Manager its called DT something but if you download or have Process Explorer you'll see it as Default Search Tab and just right click and stop process. 3. Start> Control Panel> Default Tab> KILL IT WITH FIRE!
in a long prior rush, I had also searched the registry (CAREFULLY!!!!) via W7's genuine Register Editor (Regedit) and found a pile of "SweetIm" occurences. I decided to take one of the FAQ's advices, downloaded Regsweep, and executed it with the keyword "SweetIm". That resulted in killing a few Registry entries, but did NOT remove the stubborn Tab. I also used a very good Freeware, on top of CCleaner, called Wise Registry Cleaner, to clean the regitsty after each consecutive correction act.
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.'' To Reset Firefox do the following: #Go to Firefox > Help > Troubleshooting Information. #Click the "Reset Firefox" button. #Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish. #Firefox will open with all factory defaults applied.
