This is a new thread on the problem mentioned here.
I performed all the actions to be taken as mentioned in one of the reply and hence creating a new thread because it was mentioned in the reply.
Describing the problem once again.
It started since October 2019.
I got suspicious because I started to get Russian ads on Google.
Then Google would start giving me options to translate my web pages to russian.
Then I checked my Google Maps. Under 'Your Places' I saw that one of the places I visited was Moscow.
Regardless to say I have never been to Moscow.
I changed my google password multiple times. Initially the ads didn't stopped.
In december I replaced my computer and bought a new laptop.
And the problem didn't occur in the new laptop although I had the same google account in both the machines.
But today again I got a russian ad.
I checked my google maps and I could again see Moscow as one of the places I have visited in May 2020.
I checked thoroughly and and realized google maps shows I was in russia in oct,nov,dec of 2019 and april and may of 2020.
There is only one specific address it shows where I have visited.
"Ulitsa Generala Dorokhova, 6 строение 22"
Screenshot of timeline with visits is attached.
When I had the problem in old pc, the old pc was very slow. But speed hasn't slowed in this new laptop.
Also, I changed my password today and added 2 step verification.
when I tried to add frst.txt to the post I got this error.
"The following errors occurred with your submission:

So I will add frst.txt in reply in next post.
