DNS impact with Avast premium security enabled

Avast Free Antivirus / Premium Security
1

Hi,
I have an issue since 1 week with DNS resolution that will take too much time tio execute on all my browser as well on the command line. On the command line many times my git command will return with an error:

ssh: Could not resolve hostname xxxxxx: Temporary failure in name resolution
fatal: Could not read from remote repository.

with Avast enabled, I have the following timing:

$ time dig +short www.google.com
142.250.179.100

real    0m11.096s
user    0m0.015s
sys     0m0.000s

without Avast (disabled):

$ time dig +short www.akamai.com
www.akamai.com.edgekey.net.
www.akamai.com.edgekey.net.globalredir.akadns.net.
e2915.dscx.akamaiedge.net.
104.116.97.18

real    0m1.053s
user    0m0.000s
sys     0m0.007s

Information about Avast:

Program version: 21.11.2500 (version 21.11.6809.528)
Database version: 220127-0
Interface version: 1.0.688

Windows: windows 11 Home

Could someone help to understand what’s wrong ?

Cheers

Hi,
Are installed on my 3 devices:

Avast Cleanup
VPN Avast SecureLine
Avast AntiTrack

Program version: 21.11.2500 (version 21.11.6809.528)
Database version: 220127-0
Interface version: 1.0.688

I’m running on windows 11 Home: 21H2 (build 22000.438)

I’ve used Free edition before buying the license. However, it was working perfectly until recently.

Thank you
