Hey Mark -
Yes and no. You can use the free trial and then cancel. Problem though is two-fold. First I have heard horror stories about trying to find the right person to cancel the account. When they say "no credit card required" they mean that you can also give them your bank account number. It doesn't mean no strings attached.

Second, once this product is installed in your computer you will have to live with it forever. It is like a virus that prevades all throughout your machine. Seriously though, it is difficult to unremove all the bits and peices.
