About 10 days ago, when I booted up my laptop, a pop-up from Avast suggested I update to the new version of the programme, which I did immediately.
Result : an error message from Windows Vista (0XC004D401), my Vista licence no longer recognised as valid, and Vista inoperable.
(By the way, I have Vista's Service Pack 2 installed)
I restored Vista twice - the first restoration left me with the famous black screen - and following suggestions found on internet (here and elsewhere), restored Avast to the previous version (5-dot-something).
Everything seems to be operational now... except that whatever I try, I can't update the virus database. The updating menu says my database is obsolete (110622-0), but when I ask to update, I'm told the database is already up to date (110705-0).
I'm just a plain "user" - though I've had a very steep upward learning curve over the last few days ! - and the posts on this forum have been a great help.
Can anyone help me make the final step and return to automatic database updates?
And when will there be a new Vista-proof version of Avast? I don't want to drop Avast !
