Furthermore, these "deals" are often scams. People selling "lifetime licenses" for a small fee are pocketing your money for a product that is not legitimate. Avast will eventually detect and ban the hacked license. As one user on the official Avast community forum noted: "They are the ones losing out... Those that know this is obviously not legit aren’t going to have anything to complain about when the license gets banned". You will have paid for a service that will be revoked, leaving you with no protection and a lighter wallet.
The allure of such a license is undeniable, but as is often the case, if an offer seems too good to be true, it almost certainly is. An Avast license with a validity until 2050 is not a legitimate offer from Avast. Avast does not sell licenses with such absurdly long expiration dates. Archivo De Licencia Avast Premium Security 2050
