Avast does not issue official licenses valid until 2050. The longest commercial license Avast sells is typically 3 years, with very rare, promotional “lifetime” licenses for legacy products (e.g., Avast Premier for a specific device). These lifetime offers were discontinued around 2018.

: Avast offers 30-day free trials for its Premium Security suite, allowing you to use all features without cost for a month.

Many sites offering "free license files" bundle them with "cracks" or "loaders" that may contain trojans or miners.

These are license files where the expiration date metadata has been manually altered to trick the software into displaying a long-term status.
