Diokle.prо is a rogue website that uses popular tricks to deceive users into registering for spammed browser notifications. Among the misleading text messages that this website presents to its visitors are such that ask them to click on the 'Allow' button for some event to take places, like 'connect to the Internet,' 'enable Flash Player,' 'Open the website,' 'play a video,' 'download a file' and so on. However, pressing the 'Allow' button means that Diokle.prо can start sending a huge amount of spam messages to the user's computer directly. The pop-up advertisements will show up even if no browser is launched, while their amount can be so overwhelming that it can even interfere with the affected device's regular performance.
Deleting Diokle .prо's permission to send advertisements can be done manually. However, the bigger problem is that the users have probably landed on that page because their computers are already infected with adware. An adware usually comes bundled with other software products and installs stealthily on the target system. Then, it starts generating advertisements that redirect the user to pages like Diokle.pro. Additional harmful features of adware tools are redirecting search queries and collecting the user's browsing data. Malware researchers recommend using a professional malware removal tool for devices infected with such browser hijackers.
