RPC is "Remote Procedure Call" which suggests that although the malware may be gone (just assuming the OP did that correctly) someone else has a pathway to the PC. RPC is not turned on by default in Windows operating systems, but viruses, trojans, malware and the like turn it and many other things on, as well as opening various ports.
OP, I agree with two other points in this thread.
First, you've given us almost no useful details.
Second, the best course of procedure is to reformat the hard drive and reinstall the operating system. If you have data on that drive, then you need to remove it and plug it in through a proper interface to another system that will first scan it for any remaining malware and then you can copy off the data. While it's in the other system, I'd format it right then as well. You don't want to just install the OS without a full system format on the drive so you're sure you've wiped out anything on there.
Good luck.
