You have given us very little (if any) information, past "it won't let us do anything". Have you made any attempts to remove it? If so, what specifically did you do?
I realize this is your first time posting. On the very top of where you submitted your post, there's a note (in red) which in part reads:
Note: If you're asking for technical help, please be sure to include all your system info, including operating system, model number, and any other specifics related to the problem
At this point the only help I can offer is the following removal guide. "How to remove AV Security Suite (Uninstall Guide)
Scroll down to where you see, "Automated Removal Instructions for AV Security Suite using Malwarebytes' Anti-Malware:" and follow ALL the instructions. Paying special attention to Step 2 where it notes: "It is possible that the infection you are trying to remove will not allow you to download files on the infected computer. If you run into this problem when following the steps in this guide you will need to download the files requested in this guide on another computer and then transfer them to the infected computer. You can transfer the files via a CD/DVD, external drive, or USB flash drive."
Let us know how you make out..
Best of luck..
