1] And you know what all processes are? I don't so. Besides if you see a harmfull process it is already on your system while it should be stopped before it gets there.
2] It only scans for viruses, not other malware. I suggest you also get and use Ad-Aware and Spybot s&d
3] Worms don't care about that. Many of them generate tons of random IP's, check if they excist and than try to infect those systems.
I stronlgy suggest you install a software firewall, or get a router with build in hardware firewall.
