Hey there,
I am already an Avast customer, and wanted to purchase another license for a second Win10 Machine. I've installed Free Antivirus first and started upgrading to Internet Security for a year. After firstly entering my name into the Avast In-App-Purchasing dialogue, and after entering my credentials to PayPal, I get a very strange "Javascript Confirm"-Message that reads:
"Is it OK to leave/reload this page?" which I can confirm with OK or Cancel.
No matter which of these two I choose, the Payment-Screen in the background (which until then had the rotating PayPal-ring around that lock) becomes plain white, and won't shut without shutting down all Avast services/processes.
This is quite intimidating, because I've already entered my credentials, as mentioned before. I get this exact behaviour from 2 different machines, both Win10 Home Premium, one of which has been newly installed only a few weeks ago and has an Avast Internet Security Suite up and running already.
I've locked down my PayPal account as of now. Searches for this message on the interwebz have been quite underwhelming in terms of information provided.
Has anyone got an idea what to do, or did anybody else encounter this before?
