TechWhirl (TECHWR-L) is a resource for technical writing and technical communications professionals of all experience levels and in all industries to share their experiences and acquire information.
For two decades, technical communicators have turned to TechWhirl to ask and answer questions about the always-changing world of technical communications, such as tools, skills, career paths, methodologies, and emerging industries. The TechWhirl Archives and magazine, created for, by and about technical writers, offer a wealth of knowledge to everyone with an interest in any aspect of technical communications.
.helper files are generally mini-programs/procedures that run in the background even when the main app is not running. AV software (pointless on the Mac) typically uses them, as do some other apps that have scheduling tasks running independently of, say, iCal or similar software. iTunes has its own .helper program running from login, too regardless of whether you fire up iTunes itself or not.
They are useful so long as you want them to do what they do (like human helpers...). The problem with uninstalling on the Mac is that simply sending the main app to the Trash (mac's only built-in method of uninstalling/removing software) tends to leave them in place (with 3rd party software that is).
Like our (unwanted) human "friends", the only way to get rid of them is to take direct and forceful action yourself... ;)
