Antivirus is blocking files.

[sm4llprogrammer2008]

For me Avast is being sketchy and keeps CyberCapturing never saved programs I run, those often are compiled by Small Basic 1.2 on %TEMP%.
However if you save your program, the antivirus might give up blocking, but for Avast if you close the CyberCapture window, Avast gives up and says the program is safe (only worked on SB-Prime for me)
