XML is quite strict about the consistency of all the tags (unlike html)
Actually I understnand a bit in xml, sure I checked the tag, even spell checked it using HtmlTidy, it contains an option to check xml
Also I tried to add the tag twice: right after another STANDARD tag (as suggested) and as the first tag in the "packers area" before <OUTLOOK--ScanPackers> tag. No success, but this is not very imprtant for me. The most beautiful I made it to work silently, without any intervention and without any resource degradation. Turned the ball spinning off and Avast now only about 20M in memory, that in comparison with other AV's say not bad, I know just one with less memory consumption.
Thanks for your answers guys,
Vladimir
