A query, after waiting for more than 10 days as advised above, the Avast program still warns that my offline desktop computer is unprotected. The program offers to correct this but tries to go online. Since there is no LAN card / internet connection it fails to update. Should it not after 10 days, show as registered free version? Operating system is Windows 7 SP1. Avast is the latest 18-6-3983-0 Free Home Version. What am I doing wrong or do I not understanding the program?
