Another valuable part of CCleaner is the startup tab under Tools. Often installed programs put a line in the startup routine that load something when the computer is turned on. These programs add up and can slow down the computer startup. CCleaner allows me to determine which files will load on startup. In your case, it may be important to check to see if the rogue program has inserted a line in the startup routine that will automatically download and run it again. Since the system restore to an earlier date seems to have solved the problem, that possibility is lessened, but still worth checking.
