Only the 32 bit version is affected..
If you use the 64 bit - no problemo - also simply updating to the next version deletes the malware, but not one of the registry entries. It would probably be easier for folks not familiar with the registry to use Revo uninstaller to remove this version of CCleaner, so the offending left over reg entries can be deleted. The new version of CCleaner reportedly does not see this unnecessary entry, so no luck doing it that way. I'd post the reg edit, but you can find it on search easy enough.
