AVG software missing

I have full AVG coverage, all of a sudden my computer started acting strange, locking up etc. I clicked on the AVG icon on my desktop and received a very strange pop up.  It said it was unable to access, sorry this is embarrassing.  I checked my programs, the only thing left was PC Tuneup.  Friday I received 2 phone calls telling me that my computer was at risk, it was sending out distress signals.  I need to call their support number to fix the problem.  I did not make the call.  I went online yesterday, my computer was working great.  I looked for my AVG, not there…help

Hello Lenette,
I appreciate that you have contacted us before contacting any third party support. From your account, I see that you have purchased AVG Internet Security - Unlimited, expires on 5/23/2018 and AVG PC TuneUp expires on 10/19/2017. The error message "sorry this is embarrassing" is might be because of AVG corrupted files. I've sent you an email, please follow the email instruction to connect with us remotely, we will check with your installed AVG program and we will help you to fix the AVG user interface issues and also we will check with if your computer is infected.
Best regards,
Alok.
