Whenever I open a new tab on Google Chrome I receive a pop up from Avast that a threat was blocked. I keep on getting this pop and I am not able to stop this pop up when I open a new tab. Can anyone please assist me?
Hello,
in certain situations (usually when you type into address bar, but sometimes also when you are starting a new tab), browser or some of it's plugins can attempt loading various web pages (often those that it has previously accessed). In case of search it is usually preloading pages that it thinks you may want to access, with new tab it is often due to plugins, or due to the new tab page often containing various "often accessed pages". If one of such websites (or one of its components) is malicious, Avast will block it and pop up.
This is pretty problematic to fix, as the solution has nothing to do with Avast itself, but rather the browser needs to be persuaded to not access this page (unless you just want to allow this page to load via exception, which is something that is not ideal but probably better than to uninstall Avast alltogether

). Usually the best shot is to clear browsing history (eg.
