I'm having a similar problem.
I've been a fan of CCleaner for many years. HOWEVER, in the last couple of months, analyzing takes 3 to 4 seconds. Cleaning takes anywhere from 4000 to 7000 seconds to clean. It'll work fine for a couple of days ( 13 to 26 seconds to clean) and then all of a sudden it takes 4000 to 7000 seconds to clean. That will go on for 4 to 5 days and then it starts cleaning in 13 to 26 seconds for a few days and then back to the long cleaning time. Somehow, I find this to be a little excessive. For some reason, it always hangs on IE. Session data, cookies, passwords, anything to do with IE but if it does the clean normal, it skips IE files. Mainly IE cookies. I don't understand this. I've never installed IE browser. It's the most useless untrustworthy piece of junk to ever hit the computer world as far as I'm concerned.
This morning I did something I never thought I'd do. I removed CCleaner from my 2 computers, my laptop and my Android tablet. The problem is only with the computers but I decided not to wait to see if CCleaner messed up on the laptop and tablet as well.
System Info:
System 1 - Dual Boot (Easy BDC) Windows 7 Professional 64-bit SP1. Motherboard: ASUSTeK COMPUTER INC. M5A97 R2.0 (Socket 942). CPU - AMD FX-6100. RAM - 8.00GB Single-Channel DDR3 @ 535MHz Kingston. Graphics - 1024MB ATI AMD Radeon HD 5450 (ASUStek Computer Inc) Storage - 931GB Western Digital WDC SATA Disk Device (SATA ) Win 7 64 bit.

System 2 - ASUS M3A motherboard, 4 gigs Kingston RAM, Graphics - 1024MB ATI AMD Radeon HD 5450 (ASUStek Computer Inc), Storage - WD 500 gig HDD. That's all the info I have on this system at this time. I'm currently running scans on the system and don't want to interrupt them to run Speccy.
Anyone have any ideas as to what may be happening. I would really like to get CCleaner back on all my systems if at all possible.
Thank you in advance for any ideas you may have
