Being a newbie, I apparently posted this in the wrong section of the forum:

My Avast keeps blocking <http://d.pzkysq.pink/ads.bmp?z=186912248> (the numbers at the end may change each time) every 5 minutes or less, and it keeps coming back. Avast identifies it as “infection: URL:Mal2” and gives the process as “C:\Program Files (x86)\Mozilla Firefox\firefox.exe” (here it is again, just now). Any solution?

I wanted to at least alert Avast and users so this aggravation is on the radar, and I can see that it already has a strong track
