Hi. I'm starting this topic for people who needs to keep using previous versions of AVAST (like 8 or 9) because of hardware limitations.
Since AVAST won't fix those versions...
Wrong, see: https://forum.avast.com/index.php?topic=212648.msg1439281#msg1439281
Thanks for your reply. I noticed that post refers to Avast Endpoint Protection 8, but it says nothing about Avast Free Antivirus.
Moreover, they talk about microcode updates, but I don't know if that applies to Avast Free Antivirus. If you go to Maintenance, under Update, there are two buttons: "update engine and virus definitions" and "update program". The last button if it is used change your version to a new one, for example, 8.0.1497 to 9.0.1506, so it's not a microupdate. The first button in my experience never changed the current version, it just downloads the latest definitions.
In short, I think Avast should say which versions (8, 9, etc.) are compatible with the MS patch, or if you only get that by using the latest one.
