I'm glad I found this thread, because otherwise I might have been charged for this trial.
I have an Avast Cleanup Premium trial I would like to cancel - License: 2NMFA6-S6P9Y2-49U9YJ
And I agree with everyone else, the fact I have to search Google and scour the internet to figure out how to cancel this damn thing is ridiculous, and manipulative. I won't be using Avast anymore due to this experience, and will be advising my peers to avoid it as well.
If your company has to be corrected for the most obvious of options, they planned it to be like this, and I won't encourage this behavior with my business.
But thank you to the employees responding and canceling these trials so quickly, you guys are the REAL MVPs
