Hi.  You are very very welcome. I am sending this message with added tips.  I will  follow this with another after a while, including how to cleanup. 

Before I wrap-up this case, some other tips.

Here are tips on keeping your web browsers safer.   Please make time  and read all of this.     apply the tips.

See this article on our Malwarebytes Blog
https://blog.malwarebytes.com/security-world/technology/2019/01/browser-push-notifications-feature-asking-abused/

 

You want to disable the ability of each web browser on this machine from being able to allow "push ads". That means Chrome, Firefox, or Edge browser (on Windows 10), or on Opera.

Scroll down to the tips section "How do I disable them".

 

If this pc has the Google Chrome browser, or the Brave browser, I suggest you install the Malwarebytes Browser guard for Chrome.

To get & install the Malwarebytes Browser Guard extension for Chrome,

 

Open this link in your Chrome   browser: 

https://chrome.google.com/webstore/detail/malwarebytes/ihcjicgdanjaechkgeegckofjjedodee

 

Then proceed with the setup.    [   and if you have EDGE browser, use Edge to go to the link above & also install that same Guard on it from the link above]

.

For    Mozilla Firefox, to get & install the Malwarebytes Browser Guard  Firefox extension.

Open this link in your Firefox browser:   

https://addons.mozilla.org/en-US/firefox/addon/malwarebytes/

Then proceed with the setup.

That link is for English US.¬†¬† There are other language version.¬† Just go to the very bottom right of the page and look at ‚ÄúChange language‚ÄĚ list drop down.

Cleaning up on the tools I had you use before:

To remove the FRST64  tool & its work files, do this.  Go to your Downloads folder.  Do a RIGHT-click on FRST64.exe & select RENAME & then change it to UNINSTALL.exe .
Then run that ( double click on it)  to begin the cleanup process.

Delete msert.exe.

Any other download file I had you save, you may delete.

 

Backup is your best friend.  Keep backups of your system on a regular basis to offline storage & keep those safe. https://forums.malwarebytes.com/topic/136226-backup-software/

It is not enough to just have a security program installed. Each pc user needs to practice daily safe computer and internet use.

Best  practices & malware prevention:
Follow best practices when browsing the Internet, especially on opening links coming from untrusted sources.
First rule of internet safety: slow down & think before you "click".
Never click links without first hovering your mouse over the link and seeing if it is going to an odd address ( one that does not fit or is odd looking or has typos).

Free games & free programs are like "candy". We do not accept them from "strangers".

Never open attachments that come with unexpected ( out of the blue ) email no matter how enticing.
Never open attachments from the email itself. Do not double click in the email. Always Save first and then scan with antivirus program.

Pay close attention when installing 3rd-party programs. It is important that you pay attention to the license agreements and installation screens when installing anything off of the Internet. If an installation screen offers you Custom or Advanced installation options, it is a good idea to select these as they will typically disclose what other 3rd party software will also be installed.
Take great care in every stage of the process and every offer screen, and make sure you know what it is you're agreeing to before you click "Next".

Use a Standard user account rather than an administrator-rights account when "surfing" the web.
See more info on Corrine's SecurityGarden Blog http://securitygarden.blogspot.com/p/blog-page_7.html
Don't remove your current login. Just use the new Standard-user-level one for everyday use while on the internet.

 

Keep your system and programs up to date. Several programs release security updates on a regular basis to patch vulnerabilities. Keeping your software patched up prevents attackers from being able to exploit them to drop malware.

Stay safe.¬† I wish you all the best.¬† ¬†ūüėé

Sincerely,

Maurice
