We have a set of 15 applications win32 (only executables) programmed with Delphi 2 and Delphi 4, with repository common of functions and objects (the same for all the applications).
Certain of this applications work correctly, without problem; whereas a few (6) they are congealed and they not finish never initiating. This error only takes place when the anti-virus is installed, and it is not constant, sometimes (very few) the applications they initiate normally. We try with excluding applications of the controls of the anti-virus, and do not vary anything.
Many of our clients have installed this version of corporative antivirus, like DIADIA, MAKRO, MIKRO, CATIVEN, CALLEJA, and we have several problems installing our systems. We need a solution.
Analyzing the problem, we discovered that installing the client of the anti-virus without dependency of a server, when use the option "Unload Service" of the menu, the applications work without problems. Nevertheless, installing the anti-virus following a servant, and lowering the services from Windows, the applications follow without working.
Another strange point is that using programs in order to analyze that tasks are realizing Windows (Filemnon v. 7.04), the applications that normally almost never with anti-virus, begins to work with much greater frequency.
A form in which the applications start almost always, its creating a direct access in the start of Windows, but when close the applications no longer returns to initiate. We analyze logs of the anti-virus, and it doesn´t detect these applications like virus or applications of risk.
If you need we can obtain the listing of the DLL that we used of Windows with its versions, state of registry, etc…

Windows XP SP3 (WinNT 5.01.2600)
