Kasperksy's chief technical officer Nikolay Grebennikov in a discussion Friday argued that Apple had a mandate to open iOS to non-App Store titles. He believed that Apple "simply can't continue" with its contained approach and, to eliminate the drubbing in market share, had to loosen restrictions. In spite of Apple's self-contained system keeping out rogue apps, he told Computing he didn't believe the company could properly contain malware and needed antivirus firms like Kaspersky to take care of the code.
