Well guys,
after a complete check of my pc with different antivirus and malware software clients and from a av host... and a deinstall- and reinstall from my virus protection Software G Data TP
I don´t find nothing more!
I reinstalled again Ultimate General without any problems.
My thoughts about this strange problem... maybe it was a failure in the virusdatabase after softwareupdate, who I do yesterday in the evening. Don´t know exactly..
But now it´s all ok!
Well, if the admin want he can delete this thread or he can let it for information to other useres.
thx.
By the way ... Ultimate General is a great game and I like it very much
