strange warning for malware

A friend of mine keeps getting a malware warning everytime she switches on her computer- the warning is for http://4dlmng.com/snz/sfuk210int105.exe
I searched online and nothing comes up about it. Using Avast Free and we’ve run startup scans, normal virus scans everything we can think of, downloaded malwarebytes and run scans, Windows Defender also downloaded and run.
Anyone any ideas please as to where we go next.

Please attach your logs. (AdwCleaner, MBAM, OTL and aswMBR…!!)
