One other thing. I doubt your system was externally hacked, but to be on the safe side, ensure the following:
If you're using a router, which I hope you are:
1. Reset your router back to the factory defaults, and make sure you're updated to the latest firmware.
1a. Set your routers access page with a strong random password and user name. Use upper and lowercase characters, and characters such as @#^* (if your router allows it). Make the username and passwarod at least 10 characters long each.
2. Check to see if your router has UPnP. If so, and its on by default, turn it off. UPnP allows apps to automatically forwards ports, and I personally don't trust it. If you need a port open, configure it yourself
3. If you use wireless, secure it with WPA2. If your not sure how, google it and read up on your routers manual. If your router does'nt offer WPA2 encryption, ditch it and get one that does.
4. Set your router to drop and ignore ping (ICMP Echo) requests. This way, if some hacker is scanning IP ranges for someone online, your router will ignore their ping request effectively making you steathled.
Operating System
If your using Windows, disable any unused user accounts, and password protect your user account. Make sure Windows is updated to the latest service pack and any other updates avaiable from Microsoft.
My firewall and antivrus of choice for Windows is
AntiVir Antivirus and
Comodo Firewall, both are free.
If you use Comodo, I personally install with the "firewall only" option, and deselect everything else it wants to install as extra protection. Though, that's up to you.
