根據wikipedia的內容:
http://en.wikipedia.org/wiki/AOL_Active_Virus_Shield
Active Virus Shield does lack some features of Kaspersky 6.0 (such as proactive protection and HTTP protection), and the license provided is only valid for one year, although the same email address as used initially can easily be used to renew it up to 10 times. It also does not support mail scanning when using TLS or SSL.
