thanks!

your register is valid to may 31 - 2013.
register again when there is one/two weeks left. :wink:

but only 0 days, and I can not use avast! :frowning:

is your computer time / day / month / year correct?..if not adjust and reboot

no, it’s normal.but I do not think that is the cause

try avast repair

contolpanel / ad remove / avast / uninstall / repair option…wait a minute or two and reboot

any change?

it was returned to normal. Thanks very much :smiley:
