malware – Is a bot sending queries from my computer ?

I am a complete amateur regarding cybersecurity and I have the following problem.

Quite often, when I do google research, I get the «unusual traffic» warning, saying that the queries I send are bigger than expected.

I have looked into it, and since I don’t have any vpn installed or activated, I think I contracted some sort of malware but I am not sure.

The same day the problem occurred, I was visiting a website called

This website allows one to use online virtual machines for free. I started thinking that maybe I contracted the virus from this website, and somehow I am sending queries automatically.

Could someone please check if this website is indeed the responsible for creating a malware that sends those queries ? I unfortunately don’t have the material ressources to do so.
