Did you remove it according to kaspersky instructions using there removal tool?

After using this removal tool should I have to re-install avast

Maybe, or just repair … see what works, if any?

I guess you can …

  1. attach FRST diagnostic logs and let somone take a peek inside
  2. submit a support ticket and contact avast
  3. find a AV that work

I want to contact Avast but their support team response time is so slow via mail and International call rates are so high. I have to dump my avast license :-[

phone support is from a third party…

I don’t see anything problematic in logs However, Windows Defender is active. Try to disable Windows Defender (see link) and report results.
