You’re welcome.

Well some program components may not change so if the engine changes (due to a VPS Update) it may have an unexpected result.

Unfortunately that can’t or isn’t easy to confirm/pin down. Nor do we know the fully information on the others that have experienced this issue (link in your case with an old version of avast). If this issue were widely experienced this forum would be lit up like a Christmas Tree and we haven’t seen that. It is only in the last week that I have ever seen this reported in the forums.

This is why we were pulling our hair out asking for more information as we hadn’t seen it before.

I don’t think it would be a simplistic as a reboot resolving it as some have had it happen over a few scans, presumably they shut down their systems at night.
