Is there a Blackvue App for Windows 10 yet?
I wasn't getting this in 2.50, but I am now getting this in 2.52. It claims to contain Win32/Spursint.A!cl.
If it is indeed a false positive, then generally it's something about their code that looks similar to this virus, and it's something they should change as AV companies aren't very likely to fix false positives for software this little used.
