|Try restarting in Safe Mode. Do you still get the pop-ups? If not then install & run CCleaner - use the 'tools/start-up' section to see if the nasty is listed there, you can do the same using MSCONFIG but CCleaner is tidier. Then install & scan with Malwarebytes (you can do this in Safe Mode With Networking) - remove anything it finds.|
