I was just about to post solution when I read your message thank you, infact that was my conclusion only thing was to do some backrground searches on how to get Avast not to exclude JTAlert
Not easy when your program is in French and all info on Internet is in English and tab names do not match anyway found it and put JTAlert as exclusion restart all and now OK.
Thanks for the input on TCPTest in fact Avast kept the TCPTest in the folder but deleted the Stup.exe
Up and running and will look at WSJIT_x1.5 now
Many thanks for your quick response GL GDX 73 Jacques
