agree if you looking for a free anti virus and firewall use some of those however if you want true protection i suggest investing in zone alarm security suite you can actually even take the 30 day trial and see if you really want it .
vcom systemsuite 6 has the best firewall. however most people never heard of it
nod32 is the best a/v
The Ultimate Hard Drive Utility PowerMax 4.23. (It now has the ability to clean a Boot Sector virus on the quick erase option.)
The best browser Netscape 8
