I have a License.avastlic file that was used to activate
Avast Internet Security V5.0 on one of my laptops. I know it’s
good for 3 PCS’ so I want to use it to upgrade my second laptop
which is currently running Avast Free Antivirus.
I would recommend downloading the Internet Security package, then disable you internet Connection, Uninstall the Avast Free, reboot, install Avast Internet Security.
You will be asked for the license key there. I dont think there is any other way and the link is mainly designed, I suppose, for those NOT having a key already.
Bottom line, you got more Avast that needs installed. I doubt you will need to use the cleaner sincce your just upgrading to the IS package.
Sure a bit more of a hassle than you want but not much…really 8)
