Avast asks for restart after definiton update

Last couple of days, using Avast Free (latest stable version) on Windows 10 Home 64 … Avast has asked me to restart the computer after it had downloaded definitions updates. Did something change in the defs that needs the restart and is everyone seeing this ? ? … Thanks

VPS updates can also contain updates for scan engine and minor bug fixes

Yes. I was invited to Restart Windows after an Avast update today. This happens occasionally as Avast issue bug fixes alongside virus definition updates, thus avoiding a full fat program version update.
(I see Pondus has also replied in similar vein, whilst I was typing.)

Okay, did not think this was a big issue and there is also more on it in the thread about the latest release.
