The deal with Kaspersky was discontinued. AOL now uses Mcafee for their AVS.
If you enjoyed Kaspersky, you can try their new version 7 (AOL AVS was based on 6, iirc)
free trial for 30 days. If you like it, you can just enter in a key that you later purchase to continue using it for the duration of the subscription you purchase.
Alternatively, there are free solutions, searching this forum will yield other suggestions.
