Since downloading a mp3 file yesterday (converted a YouTube video to mp3, I know i shouldn’t have) I keep getting popups from Avast just like the image I attached, and they will not go away. I have ran a full system scan and 15 files were infected and I deleted them. I am still getting these popups, however, and I got advice from a friend saying it could be a possible rootkit. How can I get rid of this?
This needs further analysis by a malware removal specialist:

There is a possible MBR infection there, please follow the steps in the thread and ensure that aswMBR is run if it fails let me know
