I downloaded the professional version of Avast two days ago, paid my 39.95. Was supposed to double click on the download button to be prompted to restart my computer and would then follow the instructions to register the product. I was sent a 'license number' to do this. I was told my money had been received, that the download was complete. At that juncture, a product called Spyware Doctor piggybacked itself onto the screen and, because I'm something of a technomoron, completely confused me. By the time I realized it was NOT part of Avast and exited out, I'd also exited out of Avast, so never got the instructions to restart my computer. I did watch a video on how to register, which someone kindly suggested on another forum, but couldn't get that to work either. I seem to be completely lost at this point. So, my question is, for anyone with the patience to deal with a technomoron: product has been paid for and downloaded. How do I now, two days later, register it??? Thank you so much!
