I'm confused as to what iSwift & iChecker are & what they do. I specifically unchecked these options. Because my recollection was they tagged every file on ones computer. That iSwift & iChecker are related to Klstream (KAVICHS). Which was mandatory in KAV5. But by unchecking iSwift & iChecker in KAV6. I was disabling Klstream (KAVICHS). But I think I'm mistaken. What are the benefits & disadvantages of enabling iSwift & iChecker technology? And what do they do? Thanks.
