Canada Post spam: you don't have mail...

Today I received an email that told me I wasn't home at 9:46 am to receive a parcel.  It was so convincing, that I clicked on the print this receipt to take to collect your parcel. This was inspite of the fact that I was indeed home at that time, and would have heard the door because the dog would have barked.

Both Malwarebytes and my firewall, responded immediatley, but I still got the .exe file.  Malwarebytes kept coming up telling me it was trying to activate this .exe. I called my computer guy, he told me how to do a system restore and I'm in the midst of scanning everything to make sure it's gone with both software.
Don't be fooled..  Apparently Canada Post has been receiving a steady stream of phone calls on this scam today.

Postscript: sorry couldn't post your response anonymous as there was an error when I tried to post it.
The important thing about this post was it talked about how to fix this problem, and yes I was not as smart as I should have been because I did click, not once but twice.  For the anonymous responder who figured I never should have clicked because I should have known better, the email was very believable and Canada Post does have my email and address connected, because I recently signed up for a business account to access their business rate plan. So it was perfectly reasonable that Canada Post would be emailing me.  My tech guy and Canada Post both said that many people were affected by this virus and weren't as lucky as I was to catch it right away.
