I use it here as a second opinion manual scan for downloaded install programs. There is no conflict.
I stand corrected. Then we are back to the OP's problem.
@ Gopher John, since you also use this software, does your Avast toolbar also spin like crazy as the OP describes when running a scan with CW? If not, we need to figure out what else is causing his/her problem.
@ marc-d-l, Do you have any other security software on your machine besides what you mentioned or in your Signature? Is SAS Pro or Free? Is anything else scanning at the time you are running the CW scan? I'm trying to problem-solve. Thanks.
