// Prompts //

• These license keys for Avast are valid up to 2023… if expired due to key blacklisted some day, do not worry, just give me one mail to notify, and another new keys will be updated as soon.
• In some situations, when you import or double click the license key file to activate, it may get stuck out there for about 1~3 minutes. Don’t worry, after that, everything will go normally.
• AVG and Piriform are all subsidiaries of Avast now
