Dear pascal dubus,
I am sorry for the late reply.
It is false alert.
As to AVG, the problem was detected and promptly fixed.
As to Kaspersky, the problem was detected and promptly fixed. But not long after that the problem has come to the fore again. And not long after that program has no problem. I guess Kaspersky's DB is unstable.
Anyway, I fix to v10.04 that v10.05 has been released. The problems are now completely solved. But, it can create problems later(It's early days yet - Kaspersky's DB).
Sorry for my English.
