Using System Restore DOES NOT remove an infection. It only makes it harder to find. System Restore actually operates only on a very few system files and settings. System Restore backs up your registry...period. I say again, System Restore will NOT uninstall a program or an Infection. System Restore is meant to restore from very RECENT changes like just day or two, not weeks.
So are you likely still infected? Probably. But since we have seen no logs we cannot say anything for sure, I just know if it was my computer I sure wouldn't be using it for anything important or store any personal files on it.
