Yahoo Email – Adds and Tracking

I use Yahoo Email since very long time, over 15 years.
I know a lot about many changes during this time.
They used advertising and I always used pop-up blocker or panel adds blocking software or plugins for Firefox and Chrome.
Lately I noticed an adware strange. It is just opening a new tab and jumps from email page to that adds page. It happens only sometimes, random.
There is no add-ons or plug-in to do that.
The computer is scanned with multiple programs against viruses, spyware and adware. The PC is clean.
I said that maybe the email address is hacked and used for advertising.
I changed the email password with a strong long one.
I have installed Avast antivirus and have me next message, after I activated the online protection module:
User generated imageUser generated imageNow, when jumps to that adds page, the page is blocked and not displayed any more, buts still jumps.
Tell me more about this  “company tracking you”.
How do I make them to don’t follow me anymore? How to “untrack”, unsubscribe and block them?
How did they found me? How do I protect myself for such future tracking actions?

Are you using free Yahoo mail?

If yes, your only option is to temporarily hide the ads, but not get rid of it.

You need to switch to the paid Yahoo mail if you do not want any ads to be seen.

No, I do not speak about this. That is easy and understandable.
I use things like these:
https://addons.mozilla.org/en-US/firefox/addon/yahoomailhideadpanel/
https://addons.mozilla.org/en-US/firefox/addon/webmail-ad-blocker/

The problem is not to see or block adds.
The problem is that while I open my emails or one the folders, the browser jumps to another unwanted page with adds.
And what I really do not like and I want to understand is that list detected by Avast of websites tracking my email address and willing to send me adds. How could that happen and how do I get rid of those "followers".
Understand.

Try to open Firefox in safe mode to see whether there are hidden addon that you cannot see.
It happnes random, so I have to wait for a while.
I restarted in safe mode with adds-on disabled.
Let me try for few days and see what's happening.
By the way, today in the morning, after I started my PC and entered in my yahoo email, it happened again, firefox was not is the safe mode at that moment.
The page that opened, it just jumped from yahoo email to that page is next:
http://main.targo12.com/?utm_medium=4e10aefcea64e87c3ae3e3ff3cb93311915828e0&utm_campaign=maya-de


And searching with Google I found is a malware:

I think that your problem maybe more than a problem from Yahoo Mail and it is not common to find hijacking of browsers from a normal user.

Try to run malwarebyte and Hitman Pro to do a full scan for malware,
I tried SpyHunter.
Found some bugs.
Removed, restart PC.
Scanned again. Clean.

Then I tried Malwarebytes.
Found other bugs.
Removed, restart PC.
Scanned again. Clean.

Let's wait few days and see if happens again that jump page witinh yahoo email.
This is strange.
From another PC I got next with Yahoo Email open:

Is the 2nd one infected too?
It is a typical browser malware for Internet Explorer.

Do you have the same problem if you another browser like Chrome, Firefox, Safari...?

What is your realtime virus scanner? Have you done a full scan for virus?
I did not try that with other browers, because default is Firefox.
I have other browsers installed, but as I use Firefox as default and becasue it happens random, is hard to say if with the other happnes. I mus monitor that, but it will take time.
In mean time I started Malwarebytes full scan.
O 2nd PC I have TrendMicro.
Hi Jackie,

Now the problem becomes interesting.
I have the problem also with the 3rd, home PC.
It is not browser related.

Today in the morning I opened from work my yahoo email and happened again, even if the PC was scanned and is clean.
I am not 100% sure, but it seems that happens 1 time per day for sure and that is the 1st time when I start the yahoo email in that day.
Have you checked your router?

It can be DNS hijack in your router.
But that cannot be at the work and home in the same time and same manner.
If you use other browsers to logon to your Yahoo mail account, will the malware ads window pop up too?
There has been a discussion for your problem in the link below.

https://forums.yahoo.net/t5/Errors/Popup-issue-main-targo12-com/td-p/17577

It seems that Yahoo! does not do any check of HTML code from their advertisers which post malware on the ads.

I do not use Yahoo Mail on browsers.
My advice is that you logon with a user with only standard user rights which cannot change any browser settings or install any software and you will be prompted for admin credentials for any kinds of installation,
I have read your proposed article. It is very informative.
And concludes that no matter what I do on my side, as proposed by last comment, no matter what PC and webbrowesr I use, it comes from yahoo. It is not related with the PC.
It is somehow inside yahoo specific client.

I will keppe it under observationa nad try for a while chorme, opera, firefox in safe and incognito mode.
And myabe Tor Browser to redirect my IP address.
Let's see what happens.
Yes.

Can only take the trial and error approach.
Today in the morning it happened again.
It is only one time, when I open the PC and the Yahoo email 1st time.
If I reset the PC it does not happen again.
It is like the 00:00 clock is reference and when is 1st time after that hour, then it happens, no matter what PC I use.
This time is another add. I used Firefox.
Unfortunately I forgot to try with Chrome, but I will try next days.
On thing interesting is the links on the bottom left that loads/scans when the email is opened.
I will try to record the screen on that region, because are many links and they come and go fast.

Here it is:

Hello Jackie,

Here is the proof that has nothing to do with a specific browser, at least not with my default Firefox.
Today in the morning I tried Chrome and it happened again.
I recorded the screen  and all the links from bottom left that are accesses by yahoo email.
Remember, it happens only 1 time per day in the morning.
