I had the same problem. But, I have noticed that the anti-virus program does something when the ccleanear is
analyzing. So, I stop the anti-virus program. Then, it shortens the time of analysis.
Are you use Avira Antivir or Active Virus Shield (I confirmed them ) ?
Then, you stop the anti-virus program or omit the ccleanear from the Anti-virus Guard.
Poor English, sorry.
