Avast antivirus support
It’s not possible to log in to the current version of Scrolls when Avast anti-virus software is running with default settings. To get around this problem, you can add Scrolls to Avast’s excluded processes list by opening the Avast interface, clicking Real-Time Shields, then clicking Web Shield. Open Expert Settings, followed by Exclusions. Under Processes to Exclude, click Add, then find your Scrolls.exe. Select it and click OK.
