If you downloaded it from the GS website, it's definately no virus. So you can make the antivirus ignore tis file (if that's possible) and/or report it to the developers of the antivirus software.

If you can't get it to run at all, you can just try renaming the DLL it to AckNet_dll or moving it to an other folder, so it's not loaded. AFAIK it's just needed for HTTP and FTP functions which are Pro only anyway, so you most likely won't need it.
