One more note on the NOD32 issue... The solution in the KB might theoretically pose a security risk, while you in fact disable all IMON's scanning on ports other than the standard HTTP ones. It is sufficient to exclude the applications nimax.exe, nimxs.exe and nisvcloc.exe (located in windows\system32 folder) from scanning. You can do this in the "Miscellaneous" tab. After that, you can turn the scanning on other ports back on. And restart Windows.
Maybe the KB article should also be updated...
