I been wondering for a while if I should also acquire Wormguard, but I can't see with my actual configuration if that would give me more security or not. I already feel a little bit paranoid now and I don't want to spend more money without a good reason. Here is what I have. L'N'S, PG,TDS-3,Port Explorer,RegDefend,Nod32, Ad-Aware and MS Antispyware. I also have Spywareblaster and Spybot S&D. Thank you for your help.
