PENDING Custom scan and odd behaviour

Recommended Posts

Win 10 1809.  EAM 9112.

I noticed this the other day, but with it being Xmas I was too busy to make a report. So I reproduced the behaviour again today.

Custom scan of C drive only and I did not use the machine in anyway while scan was running or until I looked at details of scan.

Left it to run and it completed flagging Eicar as usual.

I left the window open.

About 10 mins or so later I looked at the scan report details.

I closed the scan window and tried to open my browser. First I tried Sandboxied, then without Sandboxie.

I tried to open CD Burner XP.

It was as if something was preventing it and I am sure it was EAM after a custom scan and being left open afterwards.

I can reproduce the behaviour each time.

A definitions update occurred each time while the scan was running (just for info)

Debug logs attached

We fixed an issue that might cause this problem.
We will release a beta3 withing a few hours. Could you please try to replicate in that build ?

You will have to wait another hour or so because I have to do the custom scan first and then I wait 5 minutes or so before I can do what you ask.

I know that I struggled to open Task Manager after this last scan.

I will try now another scan and then open CD Burner XP and a few others as a test

Frank with it being Xmas/Boxing Day etc.,  I forgot to look in Reliability History when I made the first post in this thread, here is what it said.

There is nothing there for today though.

The logs do not show anything, unfortunately.

As you can replicate the problem, could you create a process dump of  a2service  with an already running, fully excluded (from monitoring) Task Manager, while the issue shows up ?

If that doesn't work, full system dump please.
