Malware Infection

hello everyone,
got a problem here, i use Avast! Free AV and Malwarebytes free,
i already scan everything and nothing was detected,
but once in a while Avast always detect this malware infection

Infection Details

URL: [link removed by admin]
Process:C:\PROGRA~1\JUSTBR~1\SPROTE~1.DLL
Infection:URL:Mal

anyone have a suggestion ?

This is related to BetterSoft adwares, that are installed together with shareware/freeware programs (like converters, downloaders, etc). The installer is trying to update or install the adware and is blocked by Avast. An example of their adware is Save By Click - http://www.2-viruses.com/remove-savebyclick.
As the installer is not a trojan, it is not properly detected by mbam and Avast.
It might be handled by Adwcleaner, Spybot S&D or Spyhunter.

If that URL is causing even an adware problem, might I suggest you stop it from being a clickable link ?

Download and run malwarebytes look down the bottom left of the page for the Free download link.

Here is the link to d/l AdwCleaner

AdwCleaner Download

Other suggested software to clean your system:

Norton Power Eraser

If these along with the above suggested tools fail to clean your system, make a copy of Windows Defender Offline on a clean PC (Not on the infected one) and run it.

Windows Defender Offline

thanks for the suggestion guys :)
