Unusual traffic from your computer network Mac Safari

Hello apple devs and users,

i will start topic which is not comfortable...

Many times when i am googlilg with safari on my brand new macbook pro, i get the google captcha and error message as mentioned in title of this post.

There is full google about this erorr, even internet provider mechanics were at my place and haven't found anything..

So i tried to delete/uninstall AVAST antivirus, and the problem with google and my traffic seem to dissapeared FOR NOW(i hope they gone for good).

I haven't found any answer which would help me, could it be safari? Or it's because of avast antivirus?

It happend to me just on macbook pro safari, not on phone, or on my windows laptop.

I would like to know more about this issue, because i don't feel safe when i'am web developer and my network is sending such things.

Thank you.
