From 21-07-2020 this error appears to me. I scanned the system with Malwarebytes and it did not detect anything, after which I reinstalled Bitdefeneder Free, but the error still persists. I contacted the technical support asking them if they have any problems with any server and they confirmed to me that the problem is not with them. The technical supporter directed me to this forum, claiming that it is the official one. At the moment I am using Windows 10 Enterpreise 32 bytes version 1909 with all the updates up to date. I want to mention that I have been using Bitdefender Free since 2017 and I had no problem with it. If there are other people who have encountered this error, please expose your problem, because it seems strange to me that a product that has worked flawlessly for 3 years has an error that apparently no one talks about (Error -1011).
