My latest setup is as follows: OS: Windows Vista Home Premium SP2 Resident: - Avira Premium Security Suite - Prevx (free) - Sandboxie (paid) On Demand: - Returnil - Shadow Defender (paid) - Online Armor (paid) I believe this is quite robust for daily normal surfing use. (no porn, no p2p). I still have a copy of DefenseWall 2.09 plus the key that I previously got from Give Away of the Day site. As I've already spent on Avira, OA Premium, and Sandboxie, I do not intend to spend again on additional security product. My question... is it still safe to use DW2.09 as an additional layer of protection despite being an older version of DW?
