A number of customers have recently found that some anti-virus software from is falsly claiming that the "boostlink.pic.exe" file is a threat to their system and being prevented from running.

This file is a component of the C compiler used by Flowcode and is used when turning the flowchart program into HEX code that will run in the chip.

Some antivirus programs disable "double extension" files, this can be changed in the settings of your antivirus program.
