I have been using the "free" AVAST! for 12 months now and was told that it would remain free AFTER the twelve months. All of a sudden I get a message saying that my computer is totally UNSAFE. After clicking the message it gives me the option to either Pay for an upgrade to PRO, Re-register the Free version, or Un-Install AVAST!. I click the Re-register option, the option window disappears, then nothing happens.
Precisely, HOW can I Re-Register the free vesion of AVAST!?
