We are developing games for Facebook platform and had an issue with authentication for one of the games. It turned out that Avast Online Security blocked Facebooks sdk.js and debug.js thus the games never loaded.
Please look into this issue, it seems that you have added Facebook to "suspicious webpages" list or smth.
Information provided here is for the purpose of helping to develop Avast's security tools. I will not be following the thread.
We will be informing our users about the flaw in Avast security and will recommend to change it for some other tool.
