about 7-8 years ago this happened to me. my antivirus started going crazy on me (mcafee at the time). every time i compiled an exe or ran anything it stopped me. i thought it broke so i disabled it. when it came time to buy a new pc, i backed up all my vb stuff (including the compiled stuff) and then i started copying it over and norton antivirus said that the compiled exe's were still infected. it sounded to me as if the virus was listening and waiting for exe's to be created or used and it would infect them at that time. now that i think about it which really sounds like something relatively easy to be able to recreate.

Im not saying this is your case (because it sounds like its just detecting the new vb exe's to be trojans not everything), but to be sure something like this isnt happening to you, you could zip a simple executable and scan it on another pc, and/or send it via email to yourself on a site that has its own virus protection so it can scan it for you.

anyway, that my 2¢ on this. good luck to you, i hope its just your WinOc.
