Avast Deep Screening stops Embarcadero RAD Studio XE creating exe files

I encountered this problem today on a PC that I do not usually use. I used it today because it had RAD Studio XE (a back level version) installed on it. The PC also happened to have “deep screening” enabled.

I was stumped when I found that RAD Studio apparently compiled and linked a C++ program successfully, but created no exe file, only the intermediate obj file.

In the process of trying to figure out what was going on, I turned off “deep screening” to speed things up and then, magically, the exe files started turning up.

Since I usually run without “deep screening” on when using RAD Studio XE6 on my usual PC, I would not normally encounter this problem, so I don’t know how long it’s been around.

Hope this helps.
