I was going to mention this before the new release but had difficulties figuring out exactly what was going on. Each time I would run ccleaner, I would be locked out of my computer. This was a problem I discovered in version 2013 and is in 2014.
From what I could find there are 3 things that need to happen.
1. Bitdefender Active Virus Control needs to be on.
2. ccleaner setting needs to be set for secure file deletion. Mine was set to simple overwrite - one pass.
3. There needs to be an executable file involved. The problem happens when this executable is being cleaned.
I have tried 3 different files of different size because I wasn't certain if it had to do with the size of the file being cleaned.
1. FileZilla FTP Client 4.59 MB
2. Quick Time Installer 39.4 MB
3. CW Shredder 520 KB
File size doesn't seem to matter because ccleaner would freeze once it began cleaning any of these 3 files.
If I set the option to Normal file deletion in ccleaner, the problem doesn't occur.
If I turn Advanced Virus Control off, the problem doesn't occur.
If there is no executable involved, the problem doesn't occur.
The problem is, this scenario keeps me from opening any applications, unable to open task manager and unable to restart my computer.
Essentially, it locks me out of my computer and I am required to perform a hard reset.
Please see attachments. 3 of the attachments show the details of the files that I used to test this. 1 image shows the setting in ccleaner. And the other shows ccleaner while trying to clean FileZilla which ends my ability to do anything on this computer. I believe Active Virus Control is the cause of this.
