Just had a virus/malware attached to this dll. Kcash.MoneyPak which is lockup/ransomware virus which gives you the fake FBI screen saying you been doing something illegal. Spyhunter4 will detect this. This is a brand new computer with two AMD 480x's in crossfire configuration. So the only place I been has been to was the AMD site to get the newest drivers after I installed Spyhunter4, Malwarebytes, Firefox, and my anti-virus from there known ip entries and not the dns addresses. Macafees seems to not detect this. I have Malwarebytes also but it hardly detects 20 percent of the known crap out there even the paid version but once in awhile it will find something the others have not setup yet in the define's. Myself I just renamed the file in case I would need it later. BTW this computer is just 3 hours old out of the box as I post this.

@Kevin: Thank you for sharing! Any idea how the malware got into your system?

Could you please upload your copy of difxapi.dll to VirusTotal? I'm interesting in seeing what the other anti-virus programs say about the file.
