Hi. I just updated to the new version and it's giving me a minor problem. When I attempted to run CCleaner, as in the past, the small window came up informing me I would have to close Firefox for the internet cache to be cleared. Fine, but when I closed FF and ran CCleaner it still informed me that the cache cleaning had been skipped. I didn't get that from the last version. What's the deal?

Hi, I just downloaded CCleaner primarily to remove some registry entries from programs I've long since uninstalled. It did ok, except for Symantec and RegClean are still there, anything I can do about it? Is it safe to manually delete those entries myself?
