Hi, I have noticed my installation of Antivirus is not updating automatically, despite definitely being set to do so. I have v4.0. I have tried using VpsUpd.exe, avast! version 4.1 and VpsUpd40.exe, avast! version 4.0 neither of them will work. the one for version 4.0 says "download the update for a later version. The one for v4.1 says “this is for a later version, upgrade to a newer version”. So I cannot update my protection and I am worried. My OS is Win XP running on a Athlon 2000+ system. What can I do please? Thank you.
