Botnet:Blacklist
« on: May 15, 2021, 01:09:06 AM »
Hello,

I am having a big problem with the Avast threat protection. Every 5 minutes a pop up appears that says that it has canceled the connection with tcp://142.250.186.68:443 which was infected with Botnet:Blacklist . The process is C:\windows\system32\svchost.exe . I have run Smart Scan multiple times but it couldnt find anything.

Two things:
1.  Whilst svchost.exe can have a legitimate reason to connect, but it is very unusual to see it in use like this. Normally you see Processes, your browser, etc.

2.  The IP address belongs to Google (Google Cloud), so I don't know if that could be misused.

https://www.google.co.uk/search?q=TCP+port+443
TCP port 443 is used for encrypted web services.

I'm wondering if some google program/service is trying to connect, but why it is using the svchost.exe service is beyond me.

You could try the - Reporting Possible False Positive File or Website - https://www.avast.com/false-positive-file-form.php function, but I don't know if it accepts IP addresses.

That said I have tried to submit it and give the link back to this topic.

Same problem at my side, but the false postiv (i think) comes with my battle.net software at start up:

Botnet:Blacklist

URl: tcp://142.250.186.68:443

Process: C:\Program Files (x86)\Battle.net\Battle.net.exe

This morning it runs normal and then comes the last virus definition and the problem begans.

Unfortunately not for me.
My father also has the same problem with the Google Ip (142.250.186.68:443).
He uses Google Earth.
