About this threat
CryptoTab is your usual suspicious browser extension that will modify your browser’s settings the second it arrives in. Users most commonly get invaded when they hastily set up free applications, and what occurs is your browser’s settings are changed and the browser adjoins the extension. The add-on will then start performing redirects and showing you more ads than you are used to. It behaves this way because that is how it gains money so it isn’t valuable to you. These types of add-on won’t directly endanger devices but that doesn’t mean they are entirely safe. You may end up with a severe malware contamination if you were redirected to a compromised web page. You really need to eliminate CryptoTab so that you don’t put your device in danger.
