CCleaner v5.00.5050 crashes Windows 7 64-bit with Bitdefender

My OFFICE system:

Manufacturer: Acer 64-bit

Model: Veriton M4630G

Operating System: Windows 7 Pro SP1

Processor: Intel Core i7-4770 CPU @ 3.40GHz 3.40GHz

RAM: 32GB (31.9 GB useable)

Antivirus: Bitdefender version 1.0.21.1099

I just loaded the latest CCleaner update to version 5.00.5050 a few days ago.

The new version prompts me to run it.

Now, everytime I run CCleaner, my pc eventually freezes up.

I can't even remote into it from home using MS RDC.

I've been using CCleaner for years. First time I'm having an issue.

HELP!!!

Perhaps go back to the previos version until Piriform sort a few of the bugs out of the new 5 build
