I don't know a whole lot about computers, I know that virus's suck! I have Norton anti-virus and personal firewall and I am networked in a small office to 3 other computers. I keep getting a warning from my personal firewall that a trojan is trying to gain access into my computer. It displays the IP address of the attacker and I add it to the restricted list on my 'Internet zone control' provided by my Norton Systemworks. BUT, the hacker keeps trying to hack my cpu from different IP's and it is VERY annoying. He hasn't got into my system BUT it has slowed down my Internet/CPU drastically!!! How can I stop this for good?
