The antivirus software CylancePROTECT blocks adexmtsv - a file associated with Fusion 360 - incorrectly classifying it as an exploit. I've tried reporting this to Cylance, but they've not acted because I'm not an administrator. Hopefully someone at Autodesk can get them to fix this!
This is the second computer I've had on which this happens, so not a one-time fluke.
The net effect of the block seems to be problems saving certain files, though I can't be sure that's the limit of the effect.
