Cumulative Update KB4493509 Windows 10 v1809 Build 17763.437 - April 9 Win Update

Did you ever check for system log events??

I suspect that is what Avira support collector is doing now. Occasional errors going back in time nothing specific

Source: avgntflt
Description: TIMEOUT<csrss.exe> C:\Program Files (x86)\Avira\Antivirus\somemodule.dll

1. Are these warnings present in system log?
2. If yes, what is datetime stamp of the most recent occurrence?

Event log
Windows / Application / user profile service – today – rest are mid March.
Windows / Set up / error / WUSA – likely the day updated with KB4493509./ none today
Windows / System / distributed COM / today / error - likely the day updated with KB4493509 as well with Service Control Manager

Administrative events as above - daily as far back as system update by MS

givin up :(

so have I - definitely some events on date of update with KB4493509 - the rest post consequential?

If any SW would give me as much as 10% of the grief like this one does, I would drop it like a hot potato.

yup, I'd ditch Avira and go with another reliable AV like Kaspersky 2019, which seemed to have released a 1903/19H1 compatible patch a day before the KB4493509 update for v1809 came out. it'll be weeks before avira would even release an updated version that would be compatible with the upcoming 1903 release

I,m quite happy with WD as only resident AV, no need for anything else. It's actually quite good comparing to any free AV.

. Still with you on this!
