Most of what I have read recommends a compete reinstall on a system that has
been breached. There may be back-doors you don't find. Take a look at -
Also set up a firewall to help prevent this in the future. There is a

There are many programs like "tripwire", "snort" "portsentry" you might
want to take a look at.
