About a week ago I began getting popups stating that a threat had been blocked. It pops up about every 15 minutes and it cycles through 3 or 4 different urls. It happens regardless of the browser, but it is the same urls that are blocked. I am running Windows 8.1.
Attach your basic logs. (MBAM, FRST and aswMBR…!!)
