Viruses and worms
1

I have been creating a c# wpf application.After I have finished it,I brought it to the firm,for testing.But after they have tried to execute it,it sad dat it is a win32 evo gen susp…Now the thing is,I scanned my computer,and it is clean.Also,when I try to use an earlier version of my program,when I start the .exe file,it scans it for 15 minutes,and allowes it.
How can I fix this?

I guess it is behaviour that trigger detection

Is this file signed? From what I remember, if you sign the file, it doesn’t detect it, unless something is triggering it.
