I am using avast home edition and it has stopped updating as of 1/4/06 I am getting an error message saying product key has expired, how do I fix this problem? or get another product/registration key so that my antivirus stays up to date??
Thanks
Kim
Yes, get a new key by registering again.

Welcome to the forums, kim059. 
You can also get information on this by right clicking the “a” ball in the Task tray, click on “About avast! …” , in the opened user interface click the “+” box or right arrow just left of “Technical support: …” , and then reading down the sub-menu to “Where to register: …”
Please come back often, learn more, and maybe help others.
