Malware in IPSEng32.dll?

Hello.

I have 3 PCs, a desktop and 2 laptops. All 3 run Windows 7 SP1 and one laptop is 32-bit, the others unsurprisingly are 64-bit. On all 3 I have NIS 2014 v21.6…32 which is fully up to date. On the desktop, I also have Emsisoft Anti-Malware (but not on the laptops) and this morning it flagged up IPSEng32.dll as containing malware. I know there has been an issue with this in the past on XP, but I thought it had been resolved. I have checked this file on all 3 PCs with both Jotti and VirusTotal and get the same result in all cases.

What exactly is going on? Why is this file showing up anywhere as malware?
I have no idea if the links will work, but I hope they do!

Thanks for any info you can give me.
