What is an AVASTLIC file?

An AVASTLIC file is a license file used by commercial versions of Avast antivirus software. It contains subscription and authorization information referenced by Avast antivirus software to register the application on the computer. AVASTLIC files include the license holder's name, the product name, and the license expiration date.

More Information

Avast sends AVASTLIC files to users as an email attachment after purchasing Avast software online. The license is required to validate the purchase of the Avast software. After validation, users can view the subscription information by selecting MAINTENANCE → Subscription within the program.

After purchasing some versions of Avast, users may receive a License.dat file instead of an AVASTLIC file. In this case, the .dat file typically has a license key that can be copied by opening the file with a text editor, such as Microsoft Notepad.

NOTE: Avast discontinued Pro Antivirus and Internet Security, and its software no longer utilizes AVASTLIC files.
