If you're getting Total Adblock pop-ups again and again, I know it can be annoying, especially when you're trying to browse normally. I would first check whether these notifications are coming from Total Adblock itself or from your browser.
If you're using Google Chrome, open Settings, go to Privacy and security, then Site settings, and select Notifications. Look for any website you don't recognize or don't want notifications from and block it. This can help stop unwanted pop-ups appearing while you browse.
You should also open Total Adblock and check its settings for notification or promotional options. If you don't want to use it anymore, you can disable its browser extension by opening Chrome's Extensions page and switching it off. You can also uninstall the extension if you no longer need it.
If the pop-ups keep coming even after disabling the extension, check whether another extension or website is causing them. Avoid clicking suspicious messages that claim your computer is infected or ask you to download something immediately.
One more thing, if you have a paid Total Adblock subscription, disabling or removing the extension may not cancel your subscription. Check your account's billing settings separately if you want to stop future payments.
These steps should help you narrow down the problem. If you tell me whether you're using Chrome, Edge, or a mobile phone, I can explain the exact steps for your device.
