Bitdefender threat error even though I never installed Bitdefender

I got this strange error today:

A problem has occured in BitDefender Threat Scanner. A file containing error information has been created at C:\Windows\Temp\BitDefender Threat Scanner.dmp

I can see the file is there. But I've never installed Bit Defender on the machine as far as I know. It's a Win2012 R2 machine I use as a development machine. There's ITBrain by Teamviewer which does malware detection. It hasn't picked anything up nor has MalwareBytes which I downloaded to scan the machine after the error. I spoke to Bitdefender and they have said they would look at it. I was wondering if anyone here had any ideas.
