I re-read your posts. First, I would like to request from you to use paragraphs and punctuation. English is not the native language for everyone in the world.
Now, about Antivir. It is not UBCD that sets it in German by default. That is how they publish their software.
Antivir Rescue System is a Linux-based tool. If you search this UBCD forum, you will see that other people already ask for that type of problem. The <alt>+<F7> is just 1 of several "desktops".
Besides this forum, you can search Antivir's forum and help, so to read about each of those possibilities. Try <alt>+F7> or <alt>+<Fn> with "Fn" being F1 to F9 keys. Somehow, one of those will show the GUI and you will be able to change the language from there.
What it keeps coming again is some resources-related problem, besides (maybe) some hardware-compatibility one. If, by default, you can't get to see Antivir's GUI, and something similar happens in other tools of the ones included in UBCD, then maybe it is not the specific hardware or UBCD, but resources.
RAM? Video memory? Video mode? Processor? Changing UBCD boot options? Changing PartedMagic boot options?
Try re-reading the posts again with not so much frustration, and maybe we can get on track again.
We are only trying to help you, and maybe we get to also improve UBCD.
I give up! you dont understand what im saying, Im having better luck else wear, and will stop using ubcd then
