I have been having this same problem for some time. I hadn't used ccleaner for a while and started to save some of my passwords in chrome (about 50). After running it recently I found myself having to log into some accounts that I thought I had saved. There are now only 5. It's funny, I printed the list about 2 weeks ago to check some things, that is how I know that I had about 50 in there. Below is the information asked of the person who created this thread.
CC v5.12.5431(64 bit)
Windows 7 Professional Service Pack 1
AVG Internet Security/AVG PC Tuneup Version 16.13.47453/AVG Framework ver 1.52.1.51616/AVG setup ver 1.52.1.51612
Chrome ver 48.0.2564.103m
I have the free version of ccleaner and only run the cleaner with no changed to the defaults.
Any help with this would be appreciated.
