Wow everyone seem to overkill on security...
Some of these software as worse as malware...make comp slowwww like hell..

I recommend only run 1 real-time anti-virus scanner...either Kaspersky/Avast/Nod32 gud enuf..
Then firewall use a router firewall best or if u prefer software then zonealarm..
Use ewido + kaspersky online scanner for on-demand scan..
plus spy-ware blaster, iespyad, firefox/opera..
and the secret weapon is Sandboxie!
Use sandboxie juz simply surf anywhere u want then finish juz clean the sandbox
tada all virus/trojan crap gone! now can go any website u wan esp. those with
lotsa prawns
