It's not an application, Jim. It's an extension that promises that you can do things like combine PDFs etc. - things you can't usually do without Acrobat (full version). Sounds good on the surface, but it's malware. It often comes along with freeware - which is why you should always pay close attention when installing any freeware. Even %#^% Java comes with a Yahoo homepage default/default search engine if you don't carefully uncheck that. I find it infuriating that Oracle, as supposedly legit software company, is stooping so low...
Anyway - back to the task at hand:
A description of EasyPDFcombine from a couple of different sites (neither of which I will provide links to, since they're all hawking removal tools and God only knows what THOSE contain!):
Once installed, Easypdfcombine adds a toolbar to your browsers. This toolbar contains such buttons as EasyPDFCombine, Share Files, Convert Files, Language Tools, and others. The application also modifies your browser settings including your home page, new tab, and default search engine. These settings are replaced with home.tb.ask.com and Ask Search. Your new search engine provides you with relevant search results, however, they also include sponsored content. Various adverts will appear on other pages that you open as well. Some of these ads will be fake. If you wish to eliminate all of these changes including the unreliable advertisements, you will have to get rid of Easypdfcombine.
Once infiltrated, EasyPDFCombine records Internet Protocol (IP) addresses (to determine geographic location), website URLs visited, pages viewed, search queries entered into search engines, and other similar information. This data may seem insignificant, however, it can contain personally identifiable details that the developers of EasyPDFCombine with third parties. It is highly probable that it will then be misused to generate revenue. Therefore, the presence of an information-tracking app such as EasyPDFCombine on your system can lead to serious privacy issues or even identity theft. Furthermore, EasyPDFCombine stealthily assigns the new tab URL, default search engine, and homepage browser settings to home.tb.ask.com. Furthermore, EasyPDFCombine prevents users from rolling back these changes by automatically reassigning the aforementioned settings when attempts are made to change them. Therefore, users are continually redirected to home.tb.ask.com, significantly diminishing their web browsing experience.
How to get rid of it:
In Firefox:
Mozilla Firefox
1. Type Command+Shift+A.
2. On the Extensions and Plugin search for the EasyPDFCombine add-on and other suspicious add-ons and remove them if located.
Done.
And if you have Chrome, check to make sure it's not there as well:
1. Click on the Customize icon (3 bar icon) next to the address bar and navigate to More tools > Extensions.
2. Search for the EasyPDFCombine extension and other suspicious extensions and remove them individually by clicking the trashcan icon next to them.
And check Safari->Preferences->Extensions to make sure it's not there as well.
