More powerful and effective than ever, CounterSpy`s award-winning spyware detection and removal is now merged with our all-new VIPRE™ antimalware technology to create the industry`s first hybrid antispyware engine.

VIPRE is a completely new, built-from-scratch antivirus and antispyware product. The antivirus engine is Sunbelt`s own creation, not licensed from another company. It has been a major undertaking, consuming millions of dollars

Kerio was going to discontinue it, but Sunbelt acquired it from Kerio to save the product from "going under".
