Avast doesn't like libcamsobj.dll why?

There’s a file in an old CAD program I use that has a file libcamsobj.dll that AVAST seems to have taken a disliking too.

When I went to load the program, a red warning pop’d up warning me about an unwanted action, then quickly dissapeared. When I tried to start the program, it said that libcamsobj.dll was missing, and that reloading the program would maybe fix the program. When I tried to copy libcamsobj.dll back to it’s correct location, I was prevented from doing so. The only way I could copy the file, and run the program was by disabling AVAST.

This only happened for the 1st time yesterday, is the latest update the problem?

Last pop up was about updates (blue background)

Since I rebooted it seems ok, when I did get the red popup there was option (I think) to recognise the action and allow it in the future, I tried clicking the line, but nothing happened, I was able to click the line below which then asked details of the files for review. Sorry for being a bit sketchy, it’s beena panic to get work out, so I do whatever it takes to get going again

Hello,
thank you for notice, false positive will be fixed in next stream update.
