I downloaded the app, ran a scan, and when I saw I had a virus I successfully bought a one-month subscription. However, no matter how many times I tried, the app could not detect that I had purchased as subscription and would not delete the virus. I even restarted the application, hit the “restore purchase” option, and everything. Do not buy!
