Great, I'm glad to hear that. Unfortunately, some files aren't always where we expect them to be. I'd feel more comfortable knowing for sure that the file is gone, but as long as it's not running anymore, it's currently not a threat.
Now that that's taken care of, you should uninstall ComboFix by going to Start > Run, typing in
combofix /u (note the space), and clicking OK.
Also, you are in need of anti-virus protection. I suggest using AVG Free, but Avast and AntiVir are good programs as well. You also need a firewall. You're vulnerable without a firewall, so you should look into getting either
ZoneAlarm,
Kerio Personal Firewall, or
Comodo. They're all good free firewalls. Just be sure you only have
one installed at a time! Download the firewall of your choice, disconnect from the internet, disable Windows Firewall, and install your new firewall.
One more thing...I should note that you are using a program called SpyHunter 3. Although it has been taken off the list, this was once considered to be a rogue program. It has been decided that they have changed their ways, but I personally don't trust them. I would advise uninstalling this product, but that is up to you.
