hard cleaned with CC cleaner
You didn't say how hard you cleaned with Ccleaner, but Ccleaner includes a Registry cleaner, and we advise not to use this or any
registry cleaner as there have been reports of them clearing out needed registry entries and messing up PCs. In addition, what they do clean up is so small that little or no advantages are noticed.
Modifying registry keys incorrectly can cause Windows instability, or make Windows unbootable. No registry cleaner is completely safe and the potential is ever present to cause more problems than they claim to fix.
Registry cleaners cannot distinguish between good and bad. If you run a registry cleaner, it will delete all those keys which are obsolete and sitting idle; but in reality, those keys may well be needed by some programs or windows at a later time.
As for your issue with not being able to access any social sites, you wouldn't happen to have a Parental Program installed that would prevent this, do you?
Just a thought!
Usually if it is one site I would suggest power cycling your router and modem by unplugging them from the wall socket and waiting a few minutes to clear the memory out, then plug the modem back in, wait a few minutes and plug the router back in and try again.
