An advertisement banner with an obscene image or extortion text to send an SMS blocking half of the screen on the desktop or in the browser is nothing more than a form of a virus. There are many ways to remove banner ads, one of them should definitely help.
Instructions
Step 1
Method number 1: first, check your computer for viruses, preferably with a deep scan. Install the latest anti-virus database. If there is no antivirus, do the following.
Step 2
Method number 2: use the free Deblocker service from Kaspersky Antivirus - https://support.kaspersky.com/viruses/deblocker. Follow the simple instructions on the site, which will ask you to enter the phone number of the scammers written on the banner (where you want to send an SMS) and the text located on the same banner
To increase the effect and completely remove the advertising banner, install the free software Kaspersky Virus Removal Tool (link in the same place).
Step 3
Method number 3: if the banner is shown only in the browser, disable all plugins (Mozilla Firefox and Opera) or add-ons (Internet Explorer) and enable them one at a time, saving the changes with the "Apply" button and restarting the browser. As soon as the banner appears after enabling the next plugin (add-on), uninstall the last included plugin. Usually such plugins impersonate "Flash" and "Video" browser add-ons.
Step 4
Method number 4: go to the Windows registry (Start - Run - regedit.exe) and find the branches there:
HKEY_LOCAL_MACHINE / Software / Microsoft / Windows / CurrentVersion / Run
HKEY_LOCAL_MACHINE / Software / Microsoft / Windows / CurrentVersion / RunOnce
HKEY_CURRENT_USER / Software / Microsoft / Windows / CurrentVersion / Run
HKEY_CURRENT_USER / Software / Microsoft / Windows / CurrentVersion / RunOnce
Check them for suspicious startup programs. If you find a virus, remove it from the registry.
