If ccleaner works for you in safe mode it points to it being perhaps a conflict with something you have running when in normal mode. This something doesn't load it's drivers when you start in safe mode.
Troubleshooting this would need you to test each startup item and could be quite time consuming. Only you can decide if you want to go down that road.
Even if you decide not to because you cannot face the hassle, don't worry about it, you're still very welcome here
Hi Gary.
No one has suggested the thread is too long. I think you misread something one of the other guys said.
A topic can get as long as it needs to until a solution is found or not, and I don't really think it was sidetracked either, as sorting out your A/V situation was relevant to generally trying to find the cause of your problem.
No one's in any hurry here to close the thread, and we're happy to take as much time as it needs as long as you don't get fed up and frustrated yourself with the fact that it isn't straightforward.
Hazel's "Safe Mode" suggestion has pinpointed where the problem lies, but it will take a bit of work to isolate the little bugger behind the problem.
And I'll second what hazel says. If you're fed up with it and want to call it a day that's fine, but you can come back to it, or any other problem, any time you like. We aren't going anywhere.
I was going to suggest running CCleaner in debug mode to see what it came up with.
Guess you guys have this one covered.
Peace!
Edit: Meanwhile, have you thought about trying an older version of CCleaner from Filehippo.com?
Perhaps start with 2.05 & see if it gives the same problem or not.
Alternatively, have you done a clean uninstall of the version you have, then deleted the x86 program files/ccleaner folder before reinstalling?
Or tried the CCleaner portable version?
These may or may not help, but I figured I would throw out a few suggestions to try... Perhaps it may help to pinpoint the problem.
