Avast pop-up constantly blocks the same threat

My avast keeps showing threat pop-ups that say it has blocked a threat.

It shows up whether I’m using the browser or not.

Infection details:
URL: http://xml.infinity-info.com/click?i=KtgdBMCbTNc_0
Infection: URL:Mal
Process: C:\Windows\SysWOW64\regsvr32.exe

I don’t know why this threat appears even if I’m not trying to access the website.
This pop-up will constantly appear about once every 30 seconds and is very very annoying.

I have scanned the computer with avast, malwarebyte anti malware, SUPERAnti-spyware and CC cleaner and the notification is still there.

How can I remove this infection? (If it is actually an infection?)

Attach your basic diagnostic logs. (MBAM, FRST and aswMBR)
