My avast4 home not only stopped auto-updating´in October or so, there is also no possibility to update manually. After downloading and running vpsupd40.exe, I first got an errorcode (unfortunately I did not write it down), and now it keeps telling me the database is already up to date, while the program still insists that the last update was 0309-9 10/13/03.
When trying to update manually from the program itself, it tells me it cannot find the file and therefore not start incremental update. WHAT CAN HAVE GONE WRONG THERE?
By the way, I run Version 4.0235 on a Windows XP home edition system.
