I just downloaded CCleaner v. 5.15513 and attempted to run it. I've been using the free version for years with no problem...and it never was as sluggish as it is now. I rebooted my computer, redownloaded the program in the event something went wrong the first time...and I don't know what to try next. My default browser is Firefox, I'm using Windows 8.1...and what else do you need to know?
Thanks in advance...
