My problem is that I got the offer for Bitdefender but it is not valid. I can remove Ultra AV but I don't have anything to replace it. I paid for my sub to kaspersky and would like a replacement that functions instead of just being with nothing or a refund. I never got a email for Ultra AV to log in or anything so it is basically causing my computer to have issues. I have issues booting it and it freezing when shutting down now. This is impacting my business.

Hello, So I miss the email where I can get Bitdefender. I noticed Ultra AV installed itself on my computer by itself. I also noticed it is starting to create files and folders by itself on every drive I have. I also noticed that it is creating a massive amount of these folders and files to the point I can't go through them and actually find my business stuff. It is becoming to massive hassle and I rather not lose my job over this. How do I get rid of this software and get bitdefender?
