I have read some references to a lot of disk activity after wakeup. I am on 5.1.889, and on boot up, I am now getting a huge amount of disk i/o, over 250,000 read i/os caused by AvastSVC. This has, I think, only started following a recent engine update a couple of weeks ago. It seems that it is now doing a major scan on startup.
Is there an explanation for this?
